This paper deals with the switching behavior of a SiC MOSFET in a TO-247 package. Based on simulations, critical parasitic inductances in the circuit layout are analyzed and their effect on the switching losses highlighted. Especially the common source inductance, a critical parameter in a TO-247 package, has a major influence on the switching energy. Crucial design guidelines for an improved double...
A flyback converter that operates in the boundary conduction mode or discontinuous conduction mode has been widely used in microinverters. Placing two flyback converters in parallel and utilizing interleaving can extend the power range of microinverters. Interleaving phases between the two converters should be carefully regulated in order to reduce the switching current ripple. In this paper, two...
Micro-inverters convert direct current (DC) from a single solar panel to alternating current (AC). Peak current control is a simple way to regulate the output current of the micro-inverter. In this way, the shape of the current reference will determine the total harmonics distortion (THD) of the output line current. However, several factors like valley switching turn-on delay and equivalent capacitor...
