There are two types of losses in MOSFET. One is conduction loss and the other one is switching loss. Conduction loss is explained in detailed here. Switching loss is not as easy as computing the conduction loss. There are many parameters to consider. You need to understand these parameters to select the correct values. However, you don’t need any more
