Introduction
Chen-Lun Yang is a notable inventor based in Hsin-Chu, Taiwan. He has made significant contributions to the field of power conversion technology, holding a total of four patents. His work focuses on enhancing the efficiency and safety of power converters.
Latest Patents
One of his latest patents is titled "Control circuit for reducing touch current of a power converter and operation method thereof." This invention includes an auxiliary pin, a zero-crossing signal generator, a frequency limiting signal generator, and a gate signal generator. The auxiliary pin receives voltage generated by an auxiliary winding of the power converter. The zero-crossing signal generator produces a zero-crossing signal based on the voltage and a first reference voltage. The frequency limiting signal generator creates a frequency limiting signal that restricts the gate control signal to a predetermined frequency. The gate signal generator then generates the gate control signal for the power switch of the converter based on the frequency limiting signal and the zero-crossing signal.
Another significant patent is related to "Control methods for over voltage protection and relevant power controllers." This disclosure presents a control method suitable for a power converter that includes a rectifier for converting alternating current into direct current. The method involves sensing the direct current input voltage and determining if it is in a valley. A detection voltage, representing the direct current input voltage, is compared with a predetermined reference voltage. If the detection voltage exceeds this reference voltage while the direct current input voltage is in the valley, an over voltage protection (OVP) signal is generated to halt the power conversion process.
