Modeling of Electronic Transformer Design with the Implementation of Single-Phase Matrix Converter Using MATLAB/Simulink

摘要

This paper investigates single-phase electronic transformer design using two stages of Single-Phase Matrix Converter (SPMC) coupled through a high frequency transformer each at the primary and secondary winding in an effort to reduce the size in the future applications of power transformer. Loads are presented in the form of passive device. The proposed system is simulated using MLS with SimPowerSystems environment. An output frequency of 1000Hz is synthesized on the input stage of the transformer using Pulse Width Modulation (PWM) technique with the output converted by another SPMC that produces 50Hz output. Commutation strategies are implemented to mitigate associated problems arising from the use of inductive load.
