Title: Innovations by Yu-Bin Wang
Introduction
Yu-Bin Wang is a notable inventor based in Hsin-Chu, Taiwan. He has made significant contributions to the field of power conversion technology. With a total of 5 patents to his name, his work focuses on enhancing the efficiency and functionality of power converters.
Latest Patents
Yu-Bin Wang's latest patents include a control circuit applicable to power converters and an operation method thereof. This control circuit features an auxiliary pin for receiving an auxiliary voltage from an auxiliary winding of a power converter. It includes a first detection unit that detects the first time point when the auxiliary voltage begins resonance, outputting a first detection signal. Additionally, a second detection unit detects when the auxiliary voltage reaches a predetermined level, generating a second detection signal. A delay time controller calculates a delay time based on the output time difference between the two detection signals, producing a driving signal with the appropriate delay. Finally, a gate control signal generator creates a gate control signal for the power switch of the power converter based on this driving signal.
Another significant patent is a pulse width modulation (PWM) control circuit applied to charge output capacitors in power converters. This circuit comprises a PWM signal generator, a first comparator, and a reference voltage modulator. The PWM signal generator controls a power switch in the converter. The first comparator receives a first reference voltage and a sensing voltage, which is proportional to the primary-side current of a transformer. When the sensing voltage matches the first reference voltage, the comparator outputs a control signal to the PWM signal generator, which then turns off the power switch. The reference voltage modulator adjusts the first reference voltage based on feedback relative to the output voltage of the power converter.
