A new zero-current-switching bridgeless PFC

2010 1st Power Electronic & Drive Systems & Technologies Conference (PEDSTC), 2010
This paper presents a new ZCS single phase bridgeless PFC which uses an auxiliary circuit for achieving zero current switching conditions for all switches of conventional bridgeless PFC. The input current is controlled by a peak current controller and output voltage is controlled with a limited band pi controller.

An improved HERIC inverter with zero-current-switching

2017 IEEE Electrical Power and Energy Conference (EPEC), 2017
In this paper, an improved HERIC inverter is proposed. It makes most switching devices operate at zero-current-switching state, by only adding auxiliary inductors on the freewheeling branch. Meanwhile, the dead-time is not required and the modulation of the system is simplified.

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 ...

Zero-Current Switching Impedance-Source DC-DC Converter

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
This paper presents a novel soft-switching technique for the galvanically isolated impedance-source full-bridge DC-DC converters. It allows reducing the turn off losses of the inverter switches, which otherwise represent a significant portion of the total power loss in such converters.

A new zero voltage and zero current power switching technique

20th Annual IEEE Power Electronics Specialists Conference, 1992
An outline is presented of work done by the authors on a novel converter topology where the power switching occurs at both zero current and zero voltage, giving it some major advantage over the present state of the art. A description is given of the application of this topology to both high and low-output-voltage converters.

Analysis and implementation of a new zero current switching flyback inverter

International Journal of Circuit Theory and Applications, 2018
Summary In this paper, a novel zero current switching (ZCS) flyback inverter in discontinuous conduction mode (DCM) is proposed. In the proposed flyback inverter, the ZCS for the primary switch is achieved by adding a simple auxiliary circuit to the conventional flyback inverter.

Switching losses of IGBTs under zero-voltage and zero-current switching

PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002
Turn-off switching losses of punch-through (PT) and nonpunch-through (NPT) IGBTs under hard switching (HS) and zero-voltage switching (ZVS) are presented and evaluated at 25/spl deg/C, 75/spl deg/C and 125/spl deg/C. A comparison between PT and NPT devices based on their internal device characteristics is given for HS and ZVS.

Zero-current-switching switched-capacitor bidirectional DC–DC converter

IEE Proceedings - Electric Power Applications, 2005
The proposed zero-current-switching switched-capacitor quasi-resonant DC-DC converter is a new type of bidirectional power flow control conversion scheme. It possesses the conventional features of resonant switched-capacitor converters: low weight, small volume, high efficiency, low EMI emission and current stress.

A family of zero current switching switched-capacitor dc-dc converters

2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010
This paper presents a new zero current switching (ZCS) technique for a family of switched-capacitor dc-dc converters. Compared to the traditional ZCS switched-capacitor dc-dc converters by inserting a magnetic core in the circuit, these new ZCS switched-capacitor dc-dc converters employ the stray inductance present in the circuit as the resonant ...

A zero-current-switching multilevel switched capacitor DC-DC converter

2011 IEEE Energy Conversion Congress and Exposition, 2011
This paper introduces a zero-current-switching multilevel switched capacitor dc-dc converter for use in high voltage gain and high temperature applications. This circuit has a reduced charge path, low switch count and low device ratings compared to many similar topologies. Furthermore, switching losses and component size are greatly reduced.
