Power Factor Correction (PFC) is becoming an integral piece of a power conversion system, particularly for high power systems. This webinar will explain reasons for poor power factor and look at ...

Electronic ballasts for fluorescent lighting deliver high efficiency and long lamp lifetimes. A new and simplified control circuit demonstrates complete control of the ballast, including all necessary ...

The NCP1603 from ON Semiconductor (Phoenix, Ariz.) combines a power-factor correction (PFC) control chip and a pulse-width modulation (PWM) control chip in a single 16-pin SOIC package. This ...

An AC/DC power supply with input power greater than 75 W requires power factor correction (PFC) to: Take the universal AC input (90 V to 264 V) and rectify that input to a DC voltage. Maintain the ...
