Development and implementation of a new DC-DC boost converter

To achieve high power density and fast transient response in well-known pulsewidth-modulation (PWM) dc?dc converters, switching frequency can be increased by decreasing switching losses through circuits called snubber cells. In the literature, there are many types of proposed snubber cells, such as RC/RCD, polarized/nonpolarized, resonant/nonresonant, and active/passive snubbers. In recent years, a number of zero-voltage transition (ZVT) and zero-current transition (ZCT) PWM converters have been proposed by adding resonant active snubbers to conventional PWM converters to combine the desirable features of both resonant and normal PWM techniques. In this study proposed converter has ZVT-ZCT PWM process on main switch and all component under soft switching.
