In recent years, significance of semiconductor module for photovoltaic power conversion systems is increasing. Especially higher output power with existing housing size of power module is important to realize further downsizing or rating upgrade for its systems. For realizing higher

For some designs, reducing circuit-board power dissipation by 25% to 30% would just be a nice outcome. For other designs, it's an absolute necessity.

Figure 1: One-Stage Approach: The driver converts an AC-rectified line voltage to the necessary DC current through a flyback transformer and filter. Unfortunately, the rectified voltage contains ripple at twice the line frequency (100 or 120 Hz).
