Abstract
A control device for a matrix converter includes an input voltage detector, an output current detector, a pulse width modulator, and an input voltage command calculator. The input voltage detector is configured to detect an input voltage of the matrix converter. The output current detector is configured to detect an output current of the matrix converter. The pulse width modulator is configured to generate a PWM pulse command signal by using the input voltage, the output current, and an output line voltage command. The input voltage command calculator is configured to calculate an input voltage command of the matrix converter.
