Implementation of a new Bi-directional three phase parallel resonant High frequency AC link converter

A Bi-directional parallel DC-AC and AC-DC resonant High frequency AC link power conversion system with non-isolated topology is designed and simulated in this paper. The results of forward and reverse flow of power are discussed in this paper. Increase in switching frequency decreases the switching losses and results in the improvement of overall efficiency. Under constant frequency 50Hz the filter designs are simplified. Simulation results based on MATLAB/SIMULINK is provided and the same is implemented in hardware and the results are verified in the laboratory.
