Abstract :
In this paper, a new way of voltage transform is designed. It directly transforms the voltage of the PWM (Pulse Width Modulation) waves whose fundamental wave is sine wave. As the fundamental wave is sine wave with 50Hz, it uses the common cold-rolled silicon steel as transformer core, which significantly reduces the cost of the voltage conversion device and improves the reliability of the voltage conversion device.
