A Zero-Voltage-Switching (ZVS) push-pull DC/DC converter for UPS

open access: closedThe 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 ...

The zero voltage switching (ZVS) critical conduction mode (CRM) buck converter with tapped-inductor

open access: closedEighteenth 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

open access: closedIAS '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

open access: closedTwentieth 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.

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

open access: closedIEEE 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

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

open access: closed2020 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.

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

open access: closedProceedings 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 ...
