Inverting Zero-Current-Switching Buck Converter

2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC), 2021
A zero current switching (ZCS) inverting buck converter is presented. Due to ZCS, the switching losses of the converter are minimized. The converter passes through four modes. The modes of operation are explained by mathematical description and with the help of the phasor u-Zi diagram. The dimensioning of the devices is explained.

Novel zero-current-switching-zero-voltage-switching converters

PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002
A new family of zero-current-switching-zero-voltage-switching (ZCSZVS) pulse-width-modulation (PWM) converters are proposed. With the proposed ZCSZVS concept, the PSPICE simulation results of the application to a single-switch three-phase PFC rectifier have been obtained and compared with those of hard-switching and ZCT applications in order to show ...

Zero-current-transition PWM DC–DC converters using new zero-current-switching PWM switch cell

IEE Proceedings - Electric Power Applications, 2006
A new family of zero-current-switching (ZCS) pulsewidth-modulated (PWM) converters, which uses a new ZCS PWM switch cell, is presented. The main switch and auxiliary switch operate at zero-current-switching turn-on and turn-off, and the all passive semiconductor devices in the ZCS-PWM converter operate at zero-voltage-switching turn-on and turn-off ...

Zero-current-switching multilevel modular switched-capacitor dc-dc converter

2009 IEEE Energy Conversion Congress and Exposition, 2009
This paper presents a quasi-resonant technique for multilevel modular switched-capacitor circuit (MMSCC) to achieve zero-current-switching (ZCS) without increasing cost and sacrificing reliability. This zero-current-switching multilevel modular switched-capacitor circuit (ZCS-MMSCC) employs the stray inductance existing in the circuit as the resonant ...

Novel zero-current-switching PWM converters

IEEE Transactions on Industrial Electronics, 1997
This paper presents a new family of pulsewidth-modulated (PWM) converters, featuring soft commutation of the semiconductors at zero current (ZC) in the transistors and zero voltage (ZV) in the rectifiers. Besides operating at constant frequency and with reduced commutation losses, these new converters have output characteristics similar to the hard ...
