POWER CONVERSION SYSTEM OF MULTI-PHASE GENERATOR AND METHOD OF OPERATING THE SAME |
摘要 |
A power conversion system of a multi-phase generator used to provide a power factor correction for a multi-phase generator. The power conversion system of the multi-phase generator includes a multi-phase power conversion unit and a control unit. The multi-phase power conversion unit receives a plurality of generator voltages and a plurality of generator currents generated from the multi-phase generator, and converts the generator voltages into a DC voltage and a DC current. The control unit controls the generator currents to linearly follow the generator voltages, therefore the power factor correction for the multi-phase generator is achieved. |

1. A power conversion system of a multi-phase generator, providing a power factor correction for a multi-phase generator, the power conversion system comprising:
a multi-phase power conversion unit configured to receive a plurality of generator voltages and a plurality of generator currents generated from the multi-phase generator, and convert the generator voltages to output a DC voltage and a DC current; and a control unit comprising:
an outer control loop configured to receive the DC voltage and one of the generator voltages, and output at least one current command;a discontinuous current limiter configured to receive the at least one current command to limit a maximum value of the at least one current command, and output the at least one current command to be a current limiting command; andan inner control loop configured to receive the DC current and the current limiting command to control the multi-phase power conversion unit; wherein the control unit is configured to control the current limiting command to control the generator currents to linearly follow the generator voltages. |
