Power electronics plays a major role in development and advancement of electric vehicles as it enables efficient energy conversion, optimal power management, maximizes the utilization of clean energy and reduces the reliance on fossil fuels. So, by leveraging power electronic technology, electric vehicles can achieve higher energy efficiency, reduced emissions and can contribute to a more sustainable and greener future of transportation which is the need of hour. One of the key components in the electric vehicle is power electronic converter which converts electrical energy between different forms and for controlling the voltage and current levels. Power electronic converters enable efficient power flow, control the speed and torque of electric motor, and facilitate regenerative braking. The first step to design a power converter is the selection of switching device which is based on the power loss analysis of the converter. The detailed study is to determine power loss with higher accuracy by considering parasitic elements and dependence factors like junction temperature, gate-source voltage, etc.

Power electronic converters are widely used in every domain for any type of power conversion. The working horse of the power conversion is a switching device. The selection of the switching device for the design is based on achieving maximum efficiency of the converter. The design or selection of the device is thus started with a model to calculate the power loss at different operating conditions. The model can be developed in many ways including the parameters from the device datasheet or the operating behavior in the complete switching cycle. The model would include determination of values of parasitic elements for power loss analysis. Thus, by developing model, power loss with higher accuracy can be predicted for device selection to achieve the maximum possible efficiency.
