Latest Patents

Junelei Li holds a patent for a "Method and circuit for constant current buck converter." This invention involves a switch mode power supply (SMPS) that includes a buck converter circuit. The circuit features a first inductor coupled to an output terminal and a switch device connected to the first inductor. The controller in this system regulates the output current by controlling the peak current in the first inductor based on the ratio between the instantaneous voltage and the average voltage at the negative output terminal. This design allows the SMPS to operate in a boundary conduction mode (BCM), maintaining a constant average output current that is largely independent of both input and output voltages while also providing a high power factor. Junelei Li has 1 patent to his name.
