Q. Advantages of McMurray Bedford Commutation

Q. Disadvantages of McMurray Bedford Commutation

Merits of McMurry Bedford Commutation :

  1. It does not need any auxiliary SCRs for commutation.
  2. It is possible to return the load energy back to source od through the feedback diodes.
  3. It is a voltage commutation and takes place instantly.

Demerits McMurry Bedford Commutation :

  1. The circuit is bulky due to the use of inductors.
  2. Energy stored in the inductors cannot be returned to source.
  3. This principle is not applicable to a three phase inverter operating in 120° mode.
