A comparative analysis of a current source inverter and a voltage source inverter suitable for induction heating and melting applications is presented. Both power supplies considered operate on the principle of load commutation. The comparison is based on criteria such as input power factor, component ratings, …Aug 5, 2021 · Load Commutated Inverter (LCI) is a system with an input thyristor bridge and an output thyristor bridge. The output bridge operates at low speed by turning on a set of 2 thyristors to pass the DC current into the generator’s stator to cause it to rotate. Fig. 5.64 depicts a load commutated inverter fed synchronous motor drive. The inverter is a current source inverter that uses T1–T6 thyristors. The voltages induced in the synchronous motor's armature are used to commutate the inverter thyristor. To get a variable Dc voltage V ds from a set source voltage V, a chopper is employed.Whether you’ve just moved to a new city or you’re sick of missing your train or bus or whathaveyou, you’ve come to the right place.

Class-A or Load commutation is prevalent in SCR circuit energized from a DC source like Series Inverter. The nature of the DC circuit should be such that when energized, the current should have a natural tendency to decay down to zero. Thus load commutation is only possible in DC circuit not in AC circuit. ….
