ABSTRACT:
A four-terminal, unity power factor, electronic rectifier module. The electronic rectifier module is self-contained and includes therein bridge diodes which form a full wave bridge rectifier, a control circuit, and a diode which components act together to draw a sinusoidal current from the line. The self-contained, four-terminal module is designed to permit a high-frequency input capacitor and a line inductor to be connected to its input terminals and a smoothing capacitor to its output terminal. The module avoids the need to provide a separate pair of power terminals for the standard filtering components, resulting in a more economical package and in an easier-to-use module.
