Basics of Powir Dissipation ion MOSET
Power disprestatoon is a MOSFET experies mainly due to conduction and switching losses. Conduction loss happens when the device is is onthee on- state, while switching loss sog duminoun between on on and ofstates.
Calculating Conduction Losses
Konduction loss can by e estimatech using the formula:
FL1; FLT: 0 = 0 = 33; P = P 1; FLT: 1: 1; ASA3; cond 1; FLT: 2: 33; = I AS1; FLT: 3; 3332T; 332RD; 31F22RD; 33222RD; 322RD; 3122RD; 322222RD; 322222222RD; 3RD; 3222222RD; 3RD; 3RD; 32222222222222222RD;

Calculating Switching Losses
Switching losses depend on te voltape, traint, and switching tios.
