ELECTRIC MOTOR DRIVING APPARATUS AND ELECTRIC MOTOR DRIVING METHOD

摘要

The present invention relates to: an electric motor driving apparatus that is provided with an inverter circuit, and a power supply relay, which is disposed on a power supply line of the inverter circuit, and which is configured from a semiconductor switch; and an electric motor driving method. The present invention is configured such that a first driver and a second driver for driving the power supply relay are provided, and the power supply relay is turned on in the cases where the first driver and/or the second driver outputs an on-signal. Consequently, interruption of power supply to the inverter circuit due to a driver failure can be suppressed.
