A single-phase bi-directional voltage source converter (VSC) is shown in the figure below. All devices are ideal. It is used to charge a battery at 400V with power of 5kW from a source V (rms), 50Hz sinusoidal AC mains at unity p.f. If its AC side interfacing inductor is 5mH and the switches are operated at 20kHz, then the phase shift between AC mains voltage and fundamental AC rms VSC voltage , in degrees, is_____.
