This paper proposes a novel hybrid modulation technique for 3-phase dual-stage bidirectional inverter to achieve electrolytic capacitor-less design for the fuel cell vehicles (FCVs) propelling system. The 3-phase bidirectional inverter consists of front-end naturally clamped current-fed dual-active-bridge dc/dc converter and back-end voltage-fed six switches 3-phase inverter. The front-end converter...
In this paper, a new resonant gate driver circuits is proposed to reduce the switching loss of high side switch in buck converter. Hard switching causes major parts of the power loss in high side switch and limits high switching frequency application of DC-DC converter. The proposed resonant gate driver behaves more like the ideal current source driver which can fast turn-on/turn-off power switch...
Flyback converters are widely used in consumer electronic products and other applications that require low cost isolated power supply with less than or around 200W output power. Transition Mode is one method to control the Flyback converters. This control method has the advantage of soft-switching turn-on, which greatly reduces the turn-on loss. This paper discusses the design of a CMOS Transition...
