Title: Yuesen Guo: Innovator in Power Factor Correction Circuits
Introduction
Yuesen Guo is a notable inventor based in Shanghai, China. He has made significant contributions to the field of electrical engineering, particularly in the development of power factor correction circuits. With a total of 3 patents to his name, Guo's work is recognized for its innovative approach to enhancing circuit performance.
Latest Patents
One of Guo's latest patents is a totem pole power factor correction circuit. This circuit includes a detection module and a control unit. The detection module consists of a first detection resistor and a first detection circuit. When a voltage difference between the two terminals of the first detection resistor is detected, an output voltage is generated. The control unit then determines the operating state of the circuit based on this output voltage. If the circuit is functioning normally, the control unit manages the on/off states of the corresponding switches according to the output voltage.
Another patent related to the totem pole power factor correction circuit involves a detection module that includes a detection resistor and a detection circuit. If the output voltage from the detection circuit exceeds an upper limit voltage threshold or falls below a lower limit voltage threshold, the control unit turns off at least a third switch and a fourth switch. This protective measure minimizes the risk of damage to the circuit, thereby enhancing its overall performance.
