The de voltage, Vdc, in Figure 1 represents the voltage generated by an array of solar cells constructed on rooftop of BN building. These solar panels are capable of producing 1.8 kW of green energy. Design a single-phase full-wave converter to deliver the generated solar power back to the utility grid (ac system) rated at 230 Vrms, 50 Hz. Assume ideal power switches are used with R = 10 2 and L is large enough to cause the load current to be essentially de. V's (cot) = Vm sin(wt) ? R L to ww 000 AC Vo Vdc DC Figure 1: Converter with RL-source load (b) Derive and prove the average output voltage equation for the converter as follows: V = 2Vm cos a [5 Marks]
