Latest Patents

Allen Cheng holds a patent for a power factor correction circuit. This circuit is designed to regulate the phase of a DC current outputted from a rectifier unit in a power supply. The circuit includes several key components such as an energy inductor, an output diode, a switch unit, a pulse width modulation unit, a sensing resistor, and a converter transformer. The converter transformer utilizes the DC current from the rectifier unit to generate an induced current. This induced current passes through the sensing resistor to produce a reference voltage. Consequently, the pulse width modulation unit can create the duty cycle for the switch unit based on this reference voltage, allowing the switch unit to effectively regulate the phase of the DC current by controlling its flowing direction.
