Power factor correction circuit with soft switched boost converter |
摘要 |
A boost converter for a power factor correction circuit having application in a DC power supply for telecommunication equipment. The boost converter has a pair of independently controlled switches such as MOSFET in series with an inductor. A capacitor is in parallel with each switch and the lossless resonant discharge of the capacitors by energy stored in the inductor eliminates switch losses at turn on. As a result the converter may be operated at higher frequencies, thereby reducing the size and cost of magnetic components in the power supply.
