MATRIX CONVERTOR, POWER GENERATION SYSTEM, AND METHOD FOR CONVERTING POWER |
摘要 |
A matrix convertor includes a power convertor, a commutation controller, an error compensator, and a compensation amount adjustor. The power convertor is disposed between input phases and output phases. The power convertor includes a plurality of bidirectional switches each including a plurality of switching elements. The commutation controller is configured to perform commutation control with respect to the plurality of switching elements of each of the plurality of bidirectional switches using a commutation pattern including a plurality of steps so as to switch connection between the input phases and the output phases through the power convertor. The error compensator is configured to calculate a compensation amount to decrease an error in an output voltage caused by the commutation control. The compensation amount adjustor is configured to decrease the compensation amount based on at least one voltage among voltages of the output phases. |
