A Load Commutated Inverter (LCI) Requires A Synchronous Motor And Contains The Line
Commutated Thyristor Rectifier Which Forms A Fully Controllable DC-current Source In
Conjunction With The Reactor In The DC Link. The DC-link Reactor Smoothes The DC Current
And Limits The DI/dt In The Event Of A Fault. The Load Commutated Thyristor Inverter
Switches The DC Current So As To Produce A Three-phase Ac System Of Variable Frequency
For Supplying The Motor. The Motor Voltages Commutate The Inverter Phase Currents. At
Low Speed, Force Commutation Is Required Because Of The Lack Of An Electrical Magnetic
Field On The Motor.
This Topology Is Used Mainly To Feed Low Speed Synchronous Motors For Single And Dual
Pinion Mills.
