A novel zero voltage switched (ZVS) buck converter using coupled inductor

Canadian Conference on Electrical and Computer Engineering 2001. Conference Proceedings (Cat. No.01TH8555), 2002
A 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., 2004
This 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 ...

A Zero Voltage Switching SVM (ZVS–SVM) Controlled Three-Phase Boost Rectifier

IEEE Transactions on Power Electronics, 2007
A zero voltage switching space vector modulation (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 ZVS-SVM for the rectifier is proposed. It can effectively suppress the reverse recovery process

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 ...

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., 2004
The 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, 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.

Zero-Voltage Switching Full-Bridge Converter With Reduced Filter Requirement and Wide ZVS Range for Variable Output Application

IEEE Transactions on Industrial Electronics, 2022
In this paper, a novel zero-voltage switching (ZVS) full-bridge converter is proposed to overcome the disadvantages of traditional phase-shifted full-bridge (PSFB) converter. In the proposed converter, a half-bridge (HB) converter with center-tap rectifier (CTR) is integrated into the traditional PSFB converter by sharing the lagging-leg switches and ...
