Abstract :
A method for designing a current source using the 12-pulse phase-controlled rectifier (PCR) is investigated. The PCR system is analysed and filter parameters are designed from this analysis. A phase-locked voltage control circuit with a fast dynamic characteristic is analysed and an optimal constant proportional-integral and measurable feedback plus feedforward (PIMF) current controller is designed using a time-weighted quadratic performance index. It is also shown from experimental results that the proposed design method gives good performance
