This paper introduces an over-modulation technique, a continuous extension of space vector PWM (SVPWM) linear control scheme for the HVDC three-phase current source rectifier (CSR). By judging the magnitude of active current vectors durations, this technique can select the current vectors in sectors and modify their active durations. It is neither necessary to store a lot of data in advance nor needs complex calculation strategy, which is very suitable to a digital implementation based on Field… CONTINUE READING
