Abstract :
We have proposed a control system in which AC components are derived from instantaneous real power (p) and instantaneous imaginary power (q) by a moving average high-pass filter. The response and accuracy of the system are very good in the case of an abrupt load change. In this paper, a new control system having an ultra high speed response is proposed for compensating a reactor input type rectifier. The system adopts a new current detection method responding in one sampling period. The operating performance of the proposed system is confirmed by simulation and laboratory model tests
