Publication number: 20250142701Abstract: A driver arrangement for powering a first load in an operation mode and a second load in a second mode. In the operation mode, a power factor correction circuitry generates a PFC output signal that powers the first load, and a switched-mode power supply is able to generate an offset signal that is superimposed over the PFC output signal for attenuating a ripple in the PFC output signal. In the second mode, the power factor correction circuitry is disabled and the switched-mode power supply is able to generate a supply power for the second load meanwhile disabled from generating the offset signal. The switched-mode power supply therefore provides a dual functionality.Type: ApplicationFiled: February 8, 2023Publication date: May 1, 2025Inventors: JIE FU, ZHIQUAN CHEN, GANG WANG

Patent number: 12273096Abstract: A driver circuit is for driving a GaN power commutation switch of a switch mode power converter. A sensing component is connected to the GaN switch for sensing a parameter such as a peak current of the power commutation.

Patent number: 12224668Abstract: A boost converter has a main energy storage inductor and a main GaN boost switch with a node between them. A pre-charging switch is connected at the output side of the main boost switch and the inductor, between the node and an output capacitor. The pre-charging switch comprises a body diode in the forward direction from the output capacitor to the node.
