The inverter that requires isolation typically consists of an isolated dc-dc and a pulse-width-modulated dc-ac stages. However, the component counts, control complexity, efficiency and power density tend to be suffered with such a two-stage configura

Parallel connection of MOSFETs is often used to increase the current handling capability of power modules. Traditional single-driver multi-chip module (SDM) needs to slow down the driving speed by using current balancing gate resistor in order to cou
