What are the performance … This types of Forced Commutation is also called load commutation as it depends upon the nature of the load. In the circuit of Fig. 11.58(a) if the thyristor is turned on, it will not turn off naturally because of the continuity of current. To turn off the thyristor a series capacitor is included in the circuit as shown in … See more Figure 11.59 illustrates the principle of parallel commutation. When the thyristor is off, C charges to Vdc as shown. As the thyristor is turned on, … See more Figure 11.60 shows the circuit of a single-phase half-bridge inverter with the inclusion of commutating capacitors C1 and C2 and indictors L1 and L2 which are tightly coupled.
