2.10. Single-Phase Half-Wave Diode Rectifier With R–L Load and Freewheeling Diode

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:

a) In the transient operation analysis, where the transient response of the circuit during its first operation cycle is presented and
