用于无桥PFC的混合低频开关

Traditionally, for the bridgeless PFC, the low-Ron Si super-junction (SJ) mosfets are utilized to reduce the loss on the low-frequency switches. However, the high cost of the low-Ron Si SJ mosfet is an issue. Therefore, this letter proposes a hybrid low frequency switch which hybrids a high-Ron and low-cost Si SJ mosfet and a high current and low-cost Si diode. This hybrid switch achieves the low ...
