Mosfet loss formula
WebMay 5, 2016 · Larger values for C snub reduce the voltage-spike amplitude further, but increase power loss in R snub. Alternatively, you can decrease the power dissipation in R snub by lowering C snub, but ringing will increase. You must weigh the trade-off between acceptable voltage-ring amplitude and R snub losses. WebBJT. There are two types of MOSFET and they are named: N-type or P-type. BJT is of two types and they are named as: PNP and NPN. MOSFET is a voltage-controlled device. BJT is a current-controlled device. The input resistance of MOSFET is high. The input resistance of BJT is low. Used in high current applications.
