Power losses calculation is important in inverter design since it provides a reference for the inverter thermal management. For MOSFET based inverters, many of MOSFET datasheets do not provide switching power losses directly. In order to estimate MOSFET switching power losses, MOSFET switching time has to be estimated firstly. The purpose of this paper is to develop an improved method for MOSFET voltage rise-time and fall-time estimation in switching power loss calculation. To obtain accurate MOSFET switching power losses, rise-time and fall-time of voltage should be estimated as accurately as possible. Two methods are introduced here, an existing method and a proposed method. A certain MOSFET product has been used for the implementation and comparison of these two methods. In the end, the calculated results are verified by experiments. Double pulse test is utilized for the experimental verification. It is proved that the estimation accuracy is improved by the proposed method.
