INVERTER DEVICE

摘要

The purpose of the present invention is to achieve stable inverter control by using one current sensor for current detection in all periods during which overmodulation control is executed. An inverter control device (3) is provided with a ³-axis current calculation unit (112) that retains a preset ³-axis current calculation equation including the direct-current as a parameter and calculates a ³-axis current by substituting a direct-current detected by the current sensor into the ³-axis current calculation equation.
