Over the past two decades plenty of resonant and quasi-resonant converters have been developed and proposed as an answer to the difficulties raised by square-wave converters, especially those related to their parasitic elements. The basic idea is to put these parasitics in use. The core of both classes of converters is a tank circuit. Unlike resonant converters, where it takes part actively in ...

The need for high gain DC-DC converters has lately increased in tandem with the utilization of renewable energy supplies. Particularly appealing are that do not require inclusion extra power switches and/or other passive elements to system. As a result, this study proposes non-isolated single switch converter ultra-high voltage (UHG) is appropriate most conversion systems, like solar installati...

In this paper, a zero-voltage and zero-current transition (ZVZCT) boost converter is presented with small number of auxiliary components, such as resonant capacitor, inductor an power switch, to produce main switch both switching (ZVS) (ZCS). Furthermore, the also has zero current switching. addition, look-up table employed implement auto-tuning technique regulate trigger position turn-on time ...

In this paper, a family of zero-voltage-transition (ZVT) magnetic coupling bidirectional DC/DC converters (BDCs) is proposed. The inductor has two functions: to serve as filter; and provide the auxiliary current. addition, phase-shifting control method used reduce conduction loss circuit. switches are all working under zero-current-switching (ZCS) conditions; thus, have no switching loss. Furth...
