Abstract
A pulse width modulation (PWM) control device for converting a first PWM signal for a two-level power conversion device to a second PWM signal for a three-level power conversion device, the three-level power conversion device including a switch, the second PWM signal driving the switch through a drive unit. The PWM control device includes an input terminal for receiving the first PWM signal for the two-level power conversion device, a conversion unit configured to convert the first PWM signal into the second PWM signal for the three-level power conversion device, and an output unit that outputs the second PWM signal to the drive unit.
