Class D- Auxiliary Commutation
1 Answer
written 6.3 years ago by |
Figure 1 shows the typical Class D commutation circuit. In this commutation method, an auxiliary thyristor $\left(T_{2}\right)$ is required to commutate the main thyristor $\left(T_{1}\right),$ Assuming ideal thyristors and the lossless components, then the waveforms are as in Fig.2. Here, inductor L is necessary to ensure the correct polarity on …
