hybrid resonant and pwm converter with high efficiency and full soft switching range
IEEE Transactions on Power Electronics, 2012Co-Authors: Jihsheng Lai, Weihan Lai, Hongmei WanAbstract:A novel soft-switching converter combining resonant half-bridge and phase-shifted pulsewidth modulation (PWM) full-bridge configuration is proposed to ensure the switches in the leading-leg operating at zero-voltage switching from true zero-load to full-load, and the switches in the lagging leg working at zero-current switching with minimum duty cycle loss and circulating conduction loss by significantly reducing leakage or Series Inductance. Experimental results of a 3.4-kW hardware prototype show that the circuit achieves true full-range soft switching with 98% peak efficiency. The hybrid resonant and PWM converter is attractive for electrical vehicle battery charger application.

hybrid half and full bridge converter with high efficiency and full soft switching range
Energy Conversion Congress and Exposition, 2011Co-Authors: Jihsheng Lai, Weihan Lai, Hongmei WanAbstract:A novel soft-switching converter combining resonant half-bridge and phase shifted full-bridge configuration is proposed to ensure the switches in the leading-leg operating at zero-voltage switching from true zero to full load, and the switches in the lagging-leg at zero-current switching with minimum duty cycle loss and circulating conduction loss by significantly reducing leakage or Series Inductance. A 3.4 kW hardware prototype has been designed, fabricated and tested to verify the validity and performance of the proposed circuit. Experimental results show that the proposed topology achieves 98% maximum efficiency, compact the output inductor size and soft-switching over a wide output voltage and current range and is attractive for electrical vehicle battery charger applications.

new power factor correction ac dc converter with reduced storage capacitor voltage
IEEE Transactions on Industrial Electronics, 2007Co-Authors: A Lazaro, A Barrado, M Sanz, V Salas, E OliasAbstract:Most of single-stage power factor correction (PFC) ac-dc converters usually present a high voltage swing on the storage capacitor. That means, high size and cost of the storage capacitor is obtained. The Series Inductance Interval (SII) PFC converters allow reducing cost and size of the storage capacitor since the capacitor voltage is lower than the output voltage and, therefore, the voltage swing is significantly reduced. In this paper, the novel single-stage SII-B-2D PFC converter is presented. In addition, this topology provides input current harmonics under EN61000-3-2 Class D limits and advantageous component count

new family of single stage pfc converters with Series Inductance interval
Power Electronics Specialists Conference, 2002Co-Authors: Antonio Manuel Lazaro, A Barrado, J Pleite, R Vazquez, E OliasAbstract:In low power applications, single-stage AC/DC converters are a good option to meet low frequency harmonic regulations because reduced cost and complexity can be obtained in comparison with the two stages approach. "The Series Inductance Interval (SII)" gives name to a new family of single-stage PFC converters focused on three main aspects: a storage capacitor voltage below the peak value of line voltage, low variation of this voltage with fine and load changes, and input current harmonics lower than the EN 61000-3-2 Class D limits for the whole load power range. Universal line voltage operation, efficiency and tight output voltage regulation have also been taken into account. This paper present the principle of operation of the SII converters besides the first experimental results.

the Series Inductance interval a new family of single stage pfc converters
International Symposium on Industrial Electronics, 2002Co-Authors: Antonio Manuel Lazaro, A Barrado, J Pleite, R Vazquez, E OliasAbstract:In low power single-phase power supplies, single-stage AC/DC converters allow meeting low frequency harmonic regulations such as EN 61000-3-2 and they result a cheaper and simpler solution than the two stages approach. The Series Inductance interval (SII) gives its name to a new family of single-stage power factor correction (PFC) converters which have been developed to obtain three features: a storage capacitor voltage below the peak value of line voltage, low variation of this voltage with line and load changes, and input current harmonics lower than the EN 61000-3-2 Class D limits for the full load power range. This paper present the principle of operation of the SII converters besides the first experimental results.
