Design of Single-Stage Flyback PFC Converter for LED Driver
Abstract: A light emitting
diode (LED) driver based on single-stage power factor correction (PFC) is presented
in this paper. The designed LED driver using flyback topology can achieve power
factor correction and constant-current drive LED in boundary conduction mode.
The circuit principle is described in detail, the formulas for MOS switch-on
time, switching frequency and the main impact factor of power factor are
proposed. The experiment results show that the designed LED driver has high
power factor, stable output and it can drive the LED with high efficiency.
