As
Fig. 2.13(d) indicates, the output current waveform is discontinuous (i.e., the current takes zero values during one cycle operation). In the circuit of
Fig. 2.16(a), a freewheeling diode is connected across the load forcing the load current to become continuous and, consequently, lower load current ripple is achieved. In the previous circuit's analyses, their operation was examined for only one cycle. However, for the circuit of
Fig. 2.16(a) the analysis will be performed in two parts:
