Power factor correction circuit with high-voltage semiconductor component |
摘要 |
A switching power supply including a power factor correction circuit comprises a rectifier, an inductor coupled in series with the rectifier, a semiconductor switch formed by a compensation device coupled in parallel with the rectifier and the inductor. The output circuit comprises a diode coupled in series with a capacitor both coupled in parallel with the semiconductor switch. An input current sensor, and a control unit for controlling the compensation device are provided.
