Title: Innovations of Chien-Ping Lu
Introduction
Chien-Ping Lu is a notable inventor based in Tainan, Taiwan. He has made significant contributions to the field of power electronics, holding a total of 12 patents. His work focuses on developing advanced circuits that enhance power conversion and control.
Latest Patents
One of his latest patents is a power converting circuit and control circuit thereof. This invention includes an upper gate switch, a transistor, a current source circuit, a comparator circuit, a delay circuit, and a pulse width modulation signal generating circuit. The transistor and the current source circuit provide a reference signal. The comparator circuit generates a comparing signal based on the reference signal and an output signal from the upper gate switch. The delay circuit produces a delay signal according to the comparing signal and a clock signal. The pulse width modulation signal generating circuit then generates a control signal for the upper gate switch based on the delay signal and the clock signal, effectively configuring the conduction status of the upper gate switch. This power converting circuit adjusts the conduction time of the upper gate switch according to the reference signal and the output signal.
Another significant invention is a charging control circuit. This circuit supplies power from an external power source to a first common node and charges a second common node from the first common node. A regulator circuit is connected between the external power source and the first common node, while a transistor is linked between the first and second common nodes. The invention detects an operational parameter of the transistor and controls an internal voltage source to generate a non-predetermined voltage difference accordingly. When the sum of the voltage at the second common node and the non-predetermined voltage meets or exceeds the reference voltage, the voltage at the first common node is regulated to a level higher than that at the second common node, ensuring the transistor operates in an optimum conductive state.
