Proposal of PM motor driving system consist of PWM inverter with voltage booster for applying to automated guided vehicle

This paper deal with a proposed PM motor driving system consist of PWM inverter with voltage booster to apply to wireless power transfer system for automated guided vehicle (AGV). This system would provide advantage that it makes to drive a PM motor and charge a battery at high efficiency against conventional system using low voltage battery because DC link voltage controlled by voltage booster at more high voltage. In addition, the voltage booster takes two roles such as DC link voltage control and battery current control. Therefore, circuit configuration can be simplified. Furthermore, the effectiveness of using SiC-MOSFET for the proposed system is suggested by evaluating efficiency of the prototype inverter by experiment. As above the investigation, it was cleared that the effectiveness of proposed PM motor driving system add the function of wireless power transfer for AGV.
