| Abstract: | A high power factor rectifier is proposed in this paper. With PWM control chip L4981A, the bridge AC/DC topologic circuit is constructed. The circuit principle is analyzed and simulated with PSpice and its design parameters are introduced. The experimental result shows that the proposed approach has many advantages, including simplified control, fewer semiconductor components, low-price and high-performance features and it is especially suitable to low cost and high power applications. |
