NCP1632 - Power Factor Controller, Interleaved, 2-Phase
www.onsemi.comPower Factor Controller, Interleaved, 2-Phase NCP1632 The NCP1632 integrates a dual MOSFET driver for interleaved PFC applications. Interleaving consists of paralleling two small stages in lieu of a bigger one, more difficult to design. This approach has several merits like the ease of implementation, the use of smaller

Power factor correction: A guide for the plant engineer
www.eaton.comWhat can I do to improve power factor? You can improve power factor by adding power factor correction capacitors to your plant distribution system. When apparent power (kVA) is greater than working power (kW), the utility must supply the excess reactive current plus the working current . Power capacitors act as reactive current generators
