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 400 V with power of 5 kW from a source Vs = 220 V (rms), 50 Hz sinusoidal AC mains at unity p.f. If its AC side interfacing inductor is 5 mH and the
switches are operated at 20 kHz, then the phase shift (δ) between AC mains voltage (Vs) and
fundamental AC rms VSC voltage (VC1), in degree, is _________.

A full-bridge converter supplying an RLE load is shown in figure. The firing angle of the bridge
converter is 120º. The supply voltage $$${v_m}\left( t \right) = 200\pi \sin \left( {100\pi t} \right)\,V,$$$ $$$R = 20 Ω, E = 800 V$$$The
inductor L is large enough to make the output current IL a smooth dc current. Switches are lossless.
The real power fed back to the source, in kW, is __________.
