Apparatus for dirving motor using distributed power and distributed power system

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a motor drive apparatus using a distributed power supply and a distributed power supply system. The motor driving apparatus using a distributed power source according to an embodiment of the present invention includes a dc / dc converter for outputting a DC power supplied from an external source to a dc stage bus, dc converter, and an inverter for converting a DC power source of the dc stage bus to an AC power source by a switching operation and driving the motor by the converted AC power source, wherein the dc / dc converter includes first and second 2 switching elements, and the first and second switching elements are alternately turned on to output external dc power to the dc stage bus. As a result, it is possible to reduce the current ripple in the motor drive apparatus using the distributed power supply and the distributed power supply system. ; Motor, drive, alternating, switching
