Switching Loss Calculation of Power MOSFET using the Estimation Technique

Soumya Sen, Souvik Saha, Angshuman Khan, Rajeev Arya

Abstract


An accurate analytical model is very important to measure the switching losses of Power
MOSFET. The perfect estimation of Power MOSFET switching loss is very difficult to predict
the efficiency of the power electronics circuit. This paper investigates the basic internal
physics of the Power MOSFET device and proposed the best possible analytical model to
calculate the power loss. The pre-existing widely accepted power loss calculation method is
found to be useless and inaccurate. In addition, the result of the pre-existing method is
overestimated to apply approximating switching time. This paper focused on new charge
parameters specification and switching time estimation technique to measure less erroneous
switching losses of Power MOSFET.
