SYSTEM AND METHOD OF COMPENSATING POWER FACTOR FOR ELECTRICAL LOADS
摘要
A power factor controller (PFC) for an electrical load such as LED lighting includes a power factor correcting converter for generating a sinusoidal input current. The PFC further includes a programmable controller for estimating a phase shifted multiplier. A current regulator generates a desired PFC current in response to an input voltage, an output load and the phase shifted and subsequently blanked multiplier. The electrical load operates in response to the sinusoidal input current based at least partially on the desired PFC current.
