Design and analysis of DC DC ZCT boost convertet with moderate output power

Abstract EN

Soft totumuration technique:; have been of yr cat i merest during the 13 it few year s in power supply switching applications.

Hl'w^cl freqt1 :ncy modulation large conduction losses, and high voltage / current stress-sa in the switches are known drawbacks The recently developed Zero-Voltage tiitnsition (ZVT,i ;uid Zero-CtirreiH :raniitiun (ZCT) pu:se width modulation tPWMj technique incorporaied soft-switching function into PW\1 converters, so that the switchm;! Susses can be reduced with uimbmmi volt see / current stresses and circulating energy The ZX\ technique tan significantly reduce the switch turn-off loss which is u.vjally (he dominant switching loss m high-power applications.

In this papers die steady stale analysis and design of the ZCT PWM boost converter are introduced.

Conlioi and drive circuit have been deigned to drive a J00 Watt ZCT PWVI boost converter Id experimentally investigate its lealures and clwiiacnshc-s
