用于并联SiC MOSFET单相DC-AC转换的混合模式自适应零电压开关

State-of-the-art soft-switching modulations such as critical conduction mode and triangular current mode increase the conduction loss of power semiconductors and require variable switching frequencies; thus, these soft-switching methods are seldom used in high-power dc–ac conversion. To achieve soft-switching while maintaining low root mean square currents, this article proposes a hybrid quadrilat...
