A novel topology for a soft-switching buck dc– dc converter with a coupled inductor is proposed. The soft-switching buck converter has advantages over the traditional hardswitching converters. The most significant advantage is that it offers a lower switching loss. This converter operates under a zero-current switching condition at turn on and a zero-voltage switching condition at turn off. It ...

In this paper, a novel zero voltage transition (ZVT) pulse width modulation (PWM) DC-DC interleaved boost converter with an active snubber cell is proposed. All of the semiconductor devices in the converter turn on and off with soft switching to reduce the switching power losses and improve the overall efficiency. Due to interleaved approach, the current stresses of main devices, the ripple of ...

This paper presents an improved Zero-Voltage-Transition Technique (ZVTTechnique) in a single-phase active power factor correction circuit based on a dc-dc boost converter topology and operated in a continuous-inductor-current mode with fixed-switching frequency control. An additional circuit for reducing the turn-off switching loss of the auxiliary switching circuit was applied. Experimental wo...

A new zero-voltage zero-current switching (ZVZCS) full-bridge phase-shifted PWM converter with controlled output rectifier is presented in this paper. Zero-voltage turn-on and zero-current turn-off for all power switches of the inverter is achieved for full load range from no-load to short circuit by using new secondary energy recovery clamp and modified PWM control strategy. Moreover by adding...

A novel interleaved boost and buck converter with zero-voltage switching (ZVS) and zero-current switching (ZCS) characteristic 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 the common soft-switching module, ...

The paper introduces soft switching of a Boost Converter which can be included in the Electrical Vehicle technology. In order to raise the motor power rating, the DC link Vehicles, there is a great need for less component stress, smaller voltage of inverter up to 400V, and higher efficiency. The conventional Boost Converter generates switching loss at turn on and off thus the whole system's eff...
