A novel zero voltage switched (ZVS) buck converter using coupled inductor
Canadian Conference on Electrical and Computer Engineering 2001. Conference Proceedings (Cat. No.01TH8555), 2002A novel zero-voltage switched (ZVS) buck converter using a coupled inductor is proposed in this paper. An additional winding is added on the same core of the output filter inductor for the purpose of commutation. The output inductor current is kept in continuous conduction mode (CCM) with small ripple.

A Zero-Voltage-Switching (ZVS) push-pull DC/DC converter for UPS
The Fifth International Conference on Power Electronics and Drive Systems, 2003. PEDS 2003., 2004This paper presents a control scheme that is very suitable for the DC/DC converter in uninterruptible power supply (UPS) systems. Based on this control scheme, a ZVS push-pull converter is proposed. With heavy load, or during the latter stage of battery discharge with light load, the DC/DC converter will operate with duty cycle fixed to near 0.5, thus ...

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 ...

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.

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.
