Abstract :
This paper describes a static synchronous compensator using a thyristor PWM current source inverter. The proposed system consists of a three-phase thyristor bridge with commutation circuit, a DC reactor, and AC filter capacitors. The three-phase thyristor bridge operates as a current-source PWM inverter with assistance of commutation circuit. The system operation was verified in detail through computer simulations with EMTP, and experiments with a scaled hardware model. The proposed system has two advantages of low switching loss and easy expansion of operation voltage through series connection of thyristors
