Single Phase FWCR : Effect of Free-Wheeling Diode
1 Answer
| written 6.4 years ago by |
Figure 1 shows the full-wave centre tap phase-controlled thyristor-circuit with inductive load and freewheeling diode. The load voltage and current-waveforms are also shown in Fig.2.

As shown in Fig.2, the thyristors are triggered at angle $\alpha .$ The variable d.c. voltage at the load is obtained by varying this firing …
