Optimising selection of power switches in PFC boost converter by MATLAB Simulink pretesting

The current paper presents an approach of selecting switches to reduce the switching losses in PFC converters. The presented concept speeds up the process of choosing the best transistor switch for PFC converters and therefore optimizes the efficiency by lowering the switching losses. The presented MATLAB Simulink model is used to determine the best transistor in a matter of efficiency. Experimental results are presented to support and verify the correct operation of the simulation model and as a reference for the simulation results. A particular example of 1500 W battery charger for ultralight electric vehicles is used as an example. A user-friendly algorithm is developed based on the proposed model for selection of the lowest losses and price transistor, suitable for a given set of input data for the considered PFC converter.
