Abstract

High performance motion controls for ac motor drives are implemented by using the resonant dc link topology. The determination of the switching mode of the inverter devices is guided by the current or voltage controllers. The early development of current or voltage controllers violated the “Pulse Polarity Consistency Rule” (PPCR) rule, which creates f l transition of the dc voltage pulse. These transitions cause voltage stress on the inverter devices. In this paper, an effective current controller “Error Magnitude Voltage Vector Correction” algorithm is presented, which achieves the elimination of voltage stress on the devices and complies with the PPCR rule. The dynamic model of estimated electromotive force EMF is developed to identify the fundamental line-line voltage zero crossing. This gives an optimal switching pattern of eight combinations 0-7 of states of the inverter devices.
