A closed loop control of three phase dual-switch buck-boost converter

This paper investigates the integrated 3-Phase AC-DC Buck-Boost converter designed to works with a great range of input AC voltages and produce a great range of output DC voltages which is similar to Conventional Converter with a sophisticated control in input section. The reduced switch converter with input Filter see through per phase voltage instead of Line voltage as in case of Conventional Converter to reduce the peak voltage stress is operated in Boost mode is discussed. Based on the results of analysis the design of converter is developed and demonstrated with 180V peak-peak input 500V output 0.5KW power and 100 KHz operating frequency and implemented with MATLAB Simulink, The voltage mode controller has been used to control the required voltage.
