Abstract

This power metering technology is developed on the high power factor buck-type PFC converter. In the application for smart LED drivers, the proposed technology and the circuit topology demonstrate that the small error of the real power evaluation, which is achieved by the excellent electrical performance with consistent power efficiency, high PF, and low THD in the dimming operation. The power evaluation coefficient is determined by the power efficiency of the PFC circuit. The small variation of the power efficiency can minimize the marginal error of the real power evaluation. Therefore, the hardware feature and the computation algorithm for the power evaluation can be simplified to meet the requirements of high accuracy and cost effective.
