Title: Innovations of Inventor Li Lian
Introduction
Li Lian is a notable inventor based in Chengdu, China. He has made significant contributions to the field of power electronics, holding a total of 3 patents. His work focuses on improving the efficiency and functionality of power converters and light drivers.
Latest Patents
One of Li Lian's latest patents is titled "Current limit peak regulation circuit for power converter with low standby power dissipation." This invention involves a current limit peak regulation circuit that provides a current limit threshold to restrict the maximum allowable peak current flowing through a main switch of the power converter. It also adjusts the current limit threshold to decrease with a reduction in the switching frequency when the power converter operates in constant voltage mode, thereby minimizing power dissipation during standby.
Another significant patent is "Light driver and the controller and driving method thereof." This invention includes a controller with a reference generating circuit that features a dimming signal converting circuit, a thermal signal converting circuit, and a selecting circuit. The dimming signal converting circuit transforms a dimming signal into a converted dimming signal, while the thermal signal converting circuit converts a thermal signal into a converted thermal signal. The selecting circuit then chooses the smaller of the two converted signals to output a reference signal.
