3-13. The half-wave rectifier with a freewheeling diode (Fig. 3-7a) has R = 122 and L = 60 mH. The source is 120 V rms at 60 Hz. (a) From the Fourier series of the half-wave rectified sine wave that appears across the load, determine the de component of the current. (b) Determine the amplitudes of the first four nonzero ac terms in the Fourier series. Comment on the results.
