Zero-voltage switching in switched current circuits

Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002
Traditionally the accuracy of switched-current circuits has been much lower than that of switched-capacitor circuits. To address this problem, an accurate high-speed switched-current sample-and-hold technique based on zero-voltage switching is presented.

A Novel Zero-Voltage-Switching PWM Full-Bridge Converter

2007 IEEE Power Electronics Specialists Conference, 2007
Introducing resonant inductance and clamping diodes into the full-bridge converter can eliminate the voltage oscillation across the rectifier diodes and increase the load range for zero- voltage-switching (ZVS) achievement. The resonant inductance is shorted and its current keeps constant when the clamping diode is conducting, and the clamping diodes ...

Variable Frequency Zero Voltage Switching Stacked-up Converter

2019 20th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM), 2019
This work describes zero voltage switching stacked-up converter as the satellite power system battery discharger. Switching processes have been analyzed. It is shown that soft switching is available in a limited range of battery voltage due to a decrease in the inductor current ripple amplitude. The soft switching range can be significantly extended by

Zero-Voltage Switching in Full-Bridge Converter

Australian Journal of Electrical and Electronics Engineering, 2008
This paper presents a comparison study of circuit topology of the voltage source type zero-voltage soft-switching (ZVS) full-bridge DC-DC power converter with an isolated high-frequency transformer employing phase-shift control. The switching power losses and voltage stress on the active devices are considerably reduced. A prototype operating at 10kHz,

A MCT-based zero voltage switching PWM inverter

Proceedings of APEC 97 - Applied Power Electronics Conference, 2002
This paper presents a MOS-controlled thyristor (MCT) based zero voltage switching (ZVS) scheme for PWM inverters. The proposed scheme utilizes a front end DC voltage notching circuit consisting of auxiliary switches and resonant components. This allows the DC link voltage to be brought to zero on command.

Zero-voltage-switched push-pull DC-DC converter

PESC '91 Record 22nd Annual IEEE Power Electronics Specialists Conference, 2002
A novel zero-voltage-switched (ZVS) push-pull DC-DC converter with two synchronous rectifiers in the secondary circuit is presented. ZVS is realized using the magnetizing current of the transformer as a current source during the commutation. The output circuit is isolated and the output voltage is controlled by pulsewidth modulation (PWM) with a ...

A novel zero-voltage switched PWM boost converter

Proceedings of PESC '95 - Power Electronics Specialist Conference, 2002
A novel, zero-voltage switched (ZVS) PWM boost converter that combines soft-switching with constant frequency operation is proposed in this paper. This converter can be operated with PWM control at a fixed frequency because ZVS operation is achieved with a simple auxiliary resonant circuit that is activated for only a small fraction of the switching ...

Novel zero-current-switching-zero-voltage-switching converters

PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002
A new family of zero-current-switching-zero-voltage-switching (ZCSZVS) pulse-width-modulation (PWM) converters are proposed. With the proposed ZCSZVS concept, the PSPICE simulation results of the application to a single-switch three-phase PFC rectifier have been obtained and compared with those of hard-switching and ZCT applications in order to show ...

Zero voltage switching full - Bridge converter topology

Intelec 2010, 2010
This paper describes a version of the Phase Shifted Full Bridge (PSFB) converter topology that achieves Zero Voltage Switching (ZVS) of the primary side controlled switches over a very wide load range, has minimal loss of output voltage due to commutation delay, that reduces the excess current flowing through the transformer and primary switches during
