A design and implementation of a novel multimode single phase matrix converter

This paper presents a multimode operation of single-phase matrix converter (SPMC) topology. It works in two modes-direct AC-AC converter and AC-DC converter. The well-known sinusoidal pulse width modulation (SPWM) scheme is used to synthesize the output. A microcontroller 89S52 is used to implement the controlling algorithm with MOSFET (IRF840) as power switching device. Prior to hardware implementation, simulations were performed to predict the behavior. Simulation is carried out in MATLAB/SIMULINK and results are presented for both modes of operation with step-up/down frequency operation for AC-AC Mode and Variable AC-DC conversion mode with different modulation index. A laboratory model test-rig of the SPMC developed gives good agreement with simulation results.
