The zero voltage switching (ZVS) critical conduction mode (CRM) buck converter with tapped-inductor
Eighteenth Annual IEEE Applied Power Electronics Conference and Exposition, 2003. APEC '03., 2004The critical conduction mode (CRM) control has some disadvantages such as the increase of switching loss and conduction loss of the main switch at extreme high/low voltage conversion applications. In this paper, a CRM buck converter with tapped inductor is proposed to overcome these problems. In this converter, both the active switch and the diode have

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, 2002Zero-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.

ZVS-IPRC: a zero voltage switching technique using secondary resonant synchronous rectifier
Proceedings of 1994 Power Electronics Specialist Conference - PESC'94, 2002A 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 ...

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.

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., 2005A 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.

A technique using a nonlinear magnetizing inductor of the transformer is proposed to achieve zero-voltage-switching (ZVS) operation. ZVS and proper transformer core reset can be realized from the resonance that exists between the parasitic capacitance and the magnetizing inductance of the transformer. DC bias current applied to the transformer makes it

This paper proposes a new soft switching synchronous Buck converter to provide complete ZVS conditions for both high and low side MOSFETs under the light- or no-load, as well as full load conditions. In the continuous conduction mode (CCM) with a heavy load current condition, the high side MOSFET is generally turned ON while the body diode of low side ...
