Extracted text: A parallel resonant inverter delivers a load power of PL = 3kW at a peak sinusoidal load voltage of V, = 220 V and at resonance. The load resistance is R = 7.5 N. The resonant frequency is fo = 30kHz. Determine (a) the de supply input current I, (b) the quality factor Qp if it is required to reduce the load power to 1500 W by frequency control so that u = 1.25, (c) the inductor L, and (d) the capacitor C.
