  • Digital-Controlled Single-Phase Transformer-Based Inverter for Non-Linear Load Applications
    IEEE Transactions on Industrial Informatics, 2013
    Co-Authors: Ming-shi Huang, Po-yi Yeh, U-ting Yeh, Meng-gu Huang
    Abstract:

    The paper presents a new digital-controlled single-phase transformer-based inverter for non-Linear Load applications. A capacitive full-bridge circuit is added to provide instant current under non-Linear Load condition and thereby reducing the harmonics significantly to meet the required harmonic standard, IEEE 519-1992, even under non-Linear Load condition. The redundant capacity, cost, size and weight of line frequency transformer can therefore be dramatically reduced. Moreover, a new integrated controller for inverter control is proposed to eliminate both DC current component and steady state error even under heavy Load condition. The proposed integrated controller consists of a Proportional (P) controller acts as voltage controller, DC offset canceller, an RMS compensator and non-Linear Load compensator. Experimental results derived from a DSP-based inverter system will be presented. The inverter rating is 1.5 kVA. It will be shown that both redundant capacity of line frequency transformer and voltage harmonics are significantly reduced even with non-Linear Load. It will also be demonstrated that the DC current component and steady state error are eliminated even under heavy Load condition. These experimental results therefore confirm the superb performance of the proposed inverter and control techniques.

    Abstract:

    The paper presents a new digital-controlled single-phase transformer-based inverter for non-Linear Load applications. A capacitive full-bridge circuit with high bandwidth is added to provide instant current under non-Linear Load condition and thereby reducing the voltage harmonics significantly to meet the harmonic standard, IEEE 519–1992. The redundant capacity, cost, size and weight of line frequency transformer can therefore be dramatically reduced. Moreover, an integrated controller is proposed to eliminate both DC current component and steady state error even under heavy Load condition. The proposed integrated controller consists of a proportional (P) controller, DC offset canceller, an RMS compensator and non-Linear Load compensator. The P-type voltage controller is used to generate the main voltage control force. DC offset canceller and RMS compensator are utilized to mitigate the effect of DC component generated by output voltage of the DC-AC module and reduce the steady-state error between voltage command and its feedback, respectively. The non-Linear Load compensator is added to generate instant current such that both the voltage harmonics and redundant capacity of transformer can be reduced for non-Linear Load application. Experimental results are carried out on a 1.5 kVA and 45∼400Hz single-phase inverter controlled by digital signal processor (TMS320F2809). It will be shown that both redundant capacity of line frequency transformer and voltage harmonics are significantly reduced even with non-Linear Load. It will also be demonstrated that the DC current component and steady state error are eliminated even under heavy Load condition. These experimental results confirm the superb performance of the proposed inverter and control techniques.

  • IROS - The mechanism of the Linear Load-sensitive continuously variable transmission with the spherical driving unit
    2011 IEEE RSJ International Conference on Intelligent Robots and Systems, 2011
    Co-Authors: Kenjiro Tadakuma, Kazuki Terada, Riichiro Tadakuma, Mitsuru Higashimori, Aiguo Ming, Makoto Shimojo, Makoto Kaneko
    Abstract:

    This paper describes Linear Load-sensitive continuously variable transmission with the spherical driving unit. This CVT mechanism consists of spherical drive, drive axis, motor housing, fixed bracket and Linear sliding plate. It changes the reduction ratio continuously by inclination angle of active rotational axis. Additionally, this Linear mechanism has a Load-sensitive function by changing inclination of active rotational axis in response to the Load. We have developed a Linear Load-sensitive continuously variable transmission and confirmed the effectiveness of the proposed mechanism.
