A composite space vector hysteresis current controller (CSVHCC) is proposed in this paper to control the three phase power converter. The duration of the modulation period is divided into two parts. One part for the carrier comparison controllers is to minimize errors at low frequency and provide a basic switching sequence. The other part for space vector hysteresis current controller (SVHCC) is to minimize errors at high frequency and its switching sequence is added to the basic switching sequence. Thus the proposed CSVHCC can make coordination between accuracy and dynamic response. The simulation and experiment shows the validity of the proposed CSVHCC.
