ABSTRACT:
The electric charge of a capacitor can be reliably discharged. Therefore, an electric discharge controller has an electrically operated machine, an inverter, a capacitor, a voltage command value generating processor for generating a voltage command value for driving, an electric discharge control processor for generating a voltage command value for electric discharge, and a driving signal generating processor. When an electric current is supplied from a direct electric current source to the inverter, the driving signal generating processor generates a driving signal on the basis of the voltage command value for driving. When the supply of the electric current from the direct electric current source to the inverter is interrupted, the driving signal generating processor generates the driving signal on the basis of the voltage command value for electric discharge, and supplies the driving signal to the inverter. The electric discharge control processor generates the voltage command value for electric discharge on the basis of the difference between a target direct current voltage and the direct current voltage. When the supply of the electric current from the direct electric current source to the inverter is interrupted, the driving signal is generated on the basis of the voltage command value for electric discharge and is supplied to the inverter.
