energy environment and advances in Power Electronics keynote address
International Conference on Performance Engineering, 2004Co-Authors: B K BoseAbstract:Power Electronics will play a significant role in global energy conservation and environmental protection in the 21st century, in addition to its traditional role in industrialization and energy systems. The world is now at the critical crossroad in the energy scenario. Energy has been the lifeblood for continual progress of human civilization. Since the industrial revolution about two centuries ago, global energy consumption has been increasing by leaps and bounds to accelerate our living standard in this planet. Currently, about 87% of our total energy is generated from fossil fuel (coal, oil and natural gas), 6% is generated in nuclear plants, and the remaining 7% comes from renewable sources (hydro and wind). Unfortunately, the world has limited fossil fuel and nuclear Power resources. Currently, our overdependence in fossil and nuclear fuels is causing pollution and safety problems in the environment, which are now dominating issues in the world. With growing energy demand, enforcement of more rigorous environmental standards and shortage of traditional energy sources, the cost of energy will tend to increase prohibitively in future jeopardizing our aspiration for high living standard. It appears that conservation of energy and correspondingly reducing the environmental pollution is of extreme importance for the future. Power Electronics can play significant roles in solving these problems. The world has enormous reserve of environmentally clean and safe renewable energy resources, such as wind and photovoltaics, where the processing of Power is highly dependent on Power Electronics. Particularly, wind energy is already competitive with that of fossil fuel because of recent technology advancement of variable speed wind turbines, Power Electronics, drives and control techniques. USA, Germany, Denmark and the developing countries like India and China have ambitious expansion programs for wind energy. The concept of future hydrogen economy and widespread use of fuel cell cars are based on conversion of wind energy and storing in the form of hydrogen. With increasing cost of gasoline, electric and hybrid vehicles that use Power Electronics extensively will help urban pollution problem. Besides these important roles, the importance of Power Electronics can hardly be overemphasized for global industrialization which is going through booming period, particularly in the developing countries. The main reason is that Power Electronics technology has gone through dramatic advancement in the recent years. Many innovations in Power semiconductor devices, converter topologies, PWM techniques, machine drives, analytical and simulation techniques, DSPs and ASIC chips, and advanced control methods have made the technology so rich today.. Very recently, artificial intelligence techniques, such as fuzzy logic, neural network and genetic algorithm have brought a new frontier of the technology. The presentation will review in the beginning the global energy generation scenario, projected depletion of fossil and nuclear fuels, environmental pollution problems, and techniques for energy conservation and environmental protection with the important role of Power Electronics. The increasingly important renewable energy sources (wind, PV and fuel cells) which are heavily dependent on advanced Power Electronics will be discussed. Then, the advances and trends of modern Power semiconductor devices, Power converters, drives and control will be reviewed systematically. Finally, the prognosis of Power Electronics for the 21st century will be highlighted.

advanced design tools for the lifetime of Power Electronics study case on motor drive application
International Power Electronics and Motion Control Conference, 2016Co-Authors: Ionut Vernica, Frede BlaabjergAbstract:In many important energy conversion systems, the Power electronic converters are proven to have high failure rates. At the same time, the failures of the Power Electronics systems are becoming more and more unacceptable because of the high cost of failures. As a consequence, an appropriate assessment of reliability performance for the Power Electronics is a crucial and emerging need, because it is the essential information for the reliability improvements, and thus reduction of the cost-of-energy. Unfortunately, there is still lack of suitable tools for the reliability assessment in Power Electronics. In this paper, an advanced design tool structure, which can acquire various reliability metrics of the Power Electronics, is proposed. The proposed design tool is based on the failure mechanisms in the critical components of the Power Electronics, and the mission profiles in the converter applications are also taken into account. Finally, a new evaluation and design example are demonstrated on a motor drive application.

Power Electronics - the key technology for renewable energy system integration
2015 International Conference on Renewable Energy Research and Applications (ICRERA), 2015Co-Authors: Frede Blaabjerg, Yongheng Yang, Xiongfei WangAbstract:The energy paradigms in many countries (e.g. Germany and Denmark) have experienced a significant change from fossil-based resources to clean renewables (e.g. wind turbines and photovoltaics) in the past few decades. The scenario of highly penetrated renewables is going to be further enhanced - Denmark expects to be 100 % fossil-free by 2050. Consequently, it is required that the production, distribution and use of the energy should be as technologically efficient as possible and incentives to save energy at the end-user should also be strengthened. In order to realize the transition smoothly and effectively, energy conversion systems, currently based on Power Electronics technology, will again play an essential role in this energy paradigm shift. Using highly efficient Power Electronics in Power generation, Power transmission/distribution and end-user application, together with advanced control solutions makes the way for renewable energies. In light of this, some of the most emerging renewable energies, e.g. wind energy and photovoltaic, which by means of Power Electronics are changing character as a major part in the electricity generation, are explored in this presentation. Issues like technology development, implementation, Power converter technologies, control of the systems, and synchronization are addressed. Special focuses are paid on the future trends in Power Electronics for those systems like how to lower the cost of energy and to develop emerging Power devices and better reliability tool.

Power Electronics and Renewable Energy Systems – a perfect match for a sustainable society
Academy Publishing Center, 2015Co-Authors: Frede BlaabjergAbstract:The energy consumption is steadily increasing very rapid due to more people on the earth, betterliving conditions as well as we are trying to live in areas where the energy demand is high. Theeconomy growth in the last century has not been possible without low prize of energy which has beenachieved by fossil fuels. Looking into the future – the fossil fuel resources have a time limit – whichcan appear faster than expected – both because of the limited resources but also because the marketcan suddenly increase the prize. Therefore there is a demand to come up with sustainable energysolutions for energy production like wind turbines, hydro Power as well as photovoltaics. At the sametime it is evident that by the use of new technology it is possible to make energy saving. In bothsituations Power Electronics are making this possible – we are using Power Electronics to interfacerenewable sources to maximize the energy yield from wind turbines and photovoltaics as well assmoothly integrate it to the grid. Also in many applications we use Power Electronics to interface a loadwith the grid and control the behavior of the electrical equipment according to the demand. In manycases Power Electronics is able to ensure a large amount of energy saving like in pumps, compressorsas well as in ventilation systems. Also the transportation gain a lot of using electricity instead of fossilfuel – clearly made possible due to the Power Electronics. Denmark is one of the societies which have been the frontier of implementing the renewabletechnology and has today covered more than 50 % of the electrical energy consumption by means ofrenewable and has as ambition to be fully independent on fossil fuels in 2050. Already in 2035 100 %of the electricity will be covered by renewables. At the same time the energy consumption has notreally increased for 20 years despite the GDP has grown by more than 60 % - much is enabled byenergy efficient technologies based on Power Electronics. So renewables and Power Electronics are aperfect tool for a sustainable society.

International Conference on Robotics and Automation, 2009Co-Authors: Michael Karpelson, Gu-yeon Wei, Robert J. WoodAbstract:Piezoelectric actuators can achieve high efficiency and Power density in very small geometries, which shows promise for microrobotic applications, such as flapping-wing robotic insects. From the perspective of Power Electronics, such actuators present two challenges: high operating voltages, ranging from tens to thousands of volts, and a low electromechanical coupling factor, which necessitates the recovery of unused electrical energy. This paper explores the Power Electronics design problem by establishing the drive requirements of piezoelectric actuators, presenting circuit topologies and control methods suitable for driving different types of piezoelectric actuators in microrobotic applications, and demonstrating experimental realizations of sub-100mg Power Electronics circuits.
