POWER FACTOR CORRECTION SWITCHING POWER SUPPLY DEVICE - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18334154 Titled 'POWER FACTOR CORRECTION SWITCHING POWER SUPPLY DEVICE'
Simplified Explanation
The abstract describes a power factor correction switching power supply device. It consists of several components, including a power factor correction circuit, capacitor circuits, a choke coil, and an electric path. The device is designed to balance common mode noise and improve power factor correction.
Original Abstract Submitted
A power factor correction switching power supply device includes a power factor correction circuit connected to an alternating-current input line, a first half-bridge capacitor circuit connected between lines of the AC input line, a second half-bridge capacitor circuit connected between lines of a direct-current output line that is closer to a load than a first output capacitor, a common mode choke coil disposed between the first output capacitor and the second half-bridge capacitor circuit, and an electric path configured to electrically connect a midpoint of the first half-bridge capacitor circuit and a midpoint of the second half-bridge capacitor circuit to form a noise balancing circuit. The noise balancing circuit has a potential different from a potential of a ground and is configured to balance common mode noise.
