Analysis and Design of a Zero-Voltage-Switching and Zero-Current-Switching Interleaved Boost Converter

IEEE Transactions on Power Electronics, 2012
A novel interleaved boost converter with zero-voltage switching (ZVS) and zero-current switching (ZCS) characteristics is proposed in this paper. By using the interleaved approach, this topology not only decreases the current stress of the main circuit device but also reduces the ripple of the input current and output voltage. Moreover, by establishing

Zero-voltage and zero-current-switching PWM combined three-level converter

2006 37th IEEE Power Electronics Specialists Conference, 2006
This paper proposes a Zero-Voltage and Zero-Current-Switching (ZVZCS) PWM combined three-level (TL) converter, which is a combination of a ZVZCS PWM TL converter with a full-bridge converter The proposed converter has advantages as follows: All power switches suffer only half of the input voltage.

Impulse Commutated Zero Current Switching Current-fed Three-phase DC/DC Converter

IEEE Transactions on Industry Applications, 2014
An impulse-commutated current-fed three-phase dc/dc converter is proposed. It is a three-inductor current divider topology that reduces the current stress of the components. The proposed converter attains zero current switching (ZCS) of the semiconductor devices via impulse commutation utilizing the circuit paracitics.
