Latest Patents

Chih-Chi Chang's latest patents include a method of controlling a power converter switched by a zero-crossing signal and a continuous conduction signal. This multi-mode controller applied to a power converter features a detection range generation module and a gate signal generation unit. The detection range generation module generates a comparison voltage based on a reference current and produces a detection signal according to the comparison voltage and a first reference voltage. When the detection signal is disabled by a zero-crossing signal, the gate signal generation unit generates a gate control signal corresponding to a quasi-resonant mode of the power converter. Conversely, when the detection signal is disabled by a continuous-conduction mode signal, the gate signal generation unit generates a gate control signal corresponding to a continuous-conduction mode of the power converter.
