Zusammenfassung:	PURPOSE:To simplify a circuit configuration and to reduce the title controller in size by providing a microcomputer having at least a PWM modulator and at least a PWM modulating function, a function for digitizing a power source voltage. CONSTITUTION:A microcomputer 100 executes calculation to obtain a current command signal according to engine control information or travel control information, fetches an output current feedback signal IF from a current detecting amplifier 7, digitally converts it by an A/D converter 103, and calculates a current deviation between the command signal and the feedback signal. Then, it calculates an output voltage command value in correspondence with the current deviation, digitizes the fetched power source voltage by an A/D converter 102 to correct it due to a variation in the power source voltage. A PWM modulator 103 built in the microcomputer 100 can obtain a pulse width modulation signal to be determined according to a correction power source voltage and a maximum power source voltage.
