Abstract
The performance of a PWM-controlled thyristor rectifier operating at unity fundamental input power factor in a PWM current source GTO inverter system for a high speed high horse power induction motor drive is analyzed. With the application of an energy rebound circuit in the DC link of the inverter for PWM control of the thyristor rectifier, a PWM control current source GTO inverter has been proposed. The principles and fundamental behavior of this inverter have also been investigated. A prototype unit of the PWM-controlled current source GTO inverter system is used to drive an 8 pole, 400 Hz, 5.5 kW three-phase induction motor. With the analytical and experimental results, the performance of the DC voltage control of the PWM-controlled thyristor rectifier for various values of the number of pulses for a half period of the supply frequency is also given in detail in this paper.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
