An array of solar cells produces 100 V dc

An array of solar cells produces 100 V dc. A single-phase AC power system is 120 V rms at 60 Hz. 
1) Determine the delay angle for the controlled converter (VdC = —100) such that 2000 W is transmitted to the AC system. Assume L is large enough to produce a current that is nearly ripple-free. The equivalent resistance is 0.811. Assume that the converter is lossless. 2) Determine the power supplied by the solar cells. 3) Estimate the value of inductance such that the peak-to-peak variation in solar cell current is less than 2.5 A. 4) Simulate the circuit in MATLAB/SIIVIULINK to verify your design. a. Plot voltages and currents at AC and DC side. b. Demonstrate that the peak-to-peak variation in solar cell current is less than 2.5 A. c. Plot power delivered to the AC system.
