| Abstract |
The paper investigates the power losses and temperature performance of MOSFET devices in a low
voltage synchronous rectifier circuit. Different devices are applied to compare their characteristics and
several auxiliary circuits are proposed to improve the efficiency of the power converter. The novel
topologies are discussed using PSPICE simulations and experimental results. It is shown that adding
an auxiliary circuit in synchronous rectifiers using MOSFETs as main devices is an effective method
to reduce the power losses. So, the power MOSFETs can operate with reduced heat sink under high
current condition. |
