ZVS-IPRC: a zero voltage switching technique using secondary resonant synchronous rectifier

Proceedings of 1994 Power Electronics Specialist Conference - PESC'94, 2002
A new group of zero voltage switching power converters called "zero voltage switching isolated partial resonant power converters" (ZVS-IPRC) are proposed to improve the conventional single end type power converter. Zero voltage switching operation is achieved by using a secondary resonant synchronous rectifier to reduce the voltage stresses and ...

Securing Full-Power-Range Zero-Voltage Switching in Both Steady-State and Transient Operations for a Dual-Active-Bridge-Based Bidirectional Electric Vehicle Charger

IEEE transactions on power electronics, 2020
Dual-active-bridge (DAB) circuit is an excellent candidate for a high-efficiency, high-power density, and bidirectional electric vehicle charger. Unlike resonant circuits employing auxiliary inductors and capacitors, DAB minimizes the usage of passive ...

Comparison of PWM zero-voltage-switching (ZVS) DC-DC converters with output isolation

IAS '95. Conference Record of the 1995 IEEE Industry Applications Conference Thirtieth IAS Annual Meeting, 2002
Zero-voltage-switching (ZVS) isolated boost power converters are analyzed and investigated in this paper. Zero-voltage-switching (ZVS) and proper core reset can be achieved through the resonance that exists between the magnetizing inductance and the parasitic capacitance. A steady-state analysis is given to illustrate the principle of operation.

A novel zero voltage switching SVM (ZVS-SVM) controlled three-phase boost rectifier

Twentieth Annual IEEE Applied Power Electronics Conference and Exposition, 2005. APEC 2005., 2005
A novel zero voltage switching SVM (ZVS-SVM) controlled three-phase boost rectifier is proposed. A branch composed of one active switch, one resonant inductor and one clamping capacitor is added to the six-switch boost rectifier. In addition, a novel space vector modulation (ZVS-SVM) for the rectifier is proposed.

Analysis and Design of a Zero-Voltage-Switched (ZVS) Quasi-Resonant Buck Converter Operating in Full-Wave Mode

2020 6th International Conference on Engineering, Applied Sciences and Technology (ICEAST), 2020
Hard-switching is typically used in most DC-DC converters, where transition of a power switch occurs when it still carries current and is subject to voltage at the same time. The hard-switching operation incurs high stress and switching losses to the device.
