Abstract:
The present disclosure is directed to a primary-controlled high power factor quasi resonant converter. The converter converts an AC power line input to a DC output to power a load, generally a string of LEDs, and may be compatible with phase-cut dimmers. The power input is fed into a transformer being controlled by a power switch. The power switch is driven by a controller having a shaping circuit. The shaping circuit uses a current generator, switched resistor and capacitor to produce a reference voltage signal. The controller drives the power switch based on the voltage reference signal, resulting in a sinusoidal input current in a primary winding of the transformer, resulting in high power factor and low total harmonic distortion for the converter.

Claim (Index 20):
The power transistor control device of  claim 17 , wherein the means for generating the second signal based on the first signal comprises one of a means for generating a current based on the first signal and a means for multiplying the first signal by a gain.
