Latest Patents

Yen Hui Wang holds a patent for a "Controller of buck-boost conversion circuit and mode switching method thereof." This invention provides a controller that manages the operations of multiple switches within a buck-boost conversion circuit. It effectively converts an input voltage into an output voltage while supplying an output current. The controller features a slope compensation circuit, a control loop, and a mode switching circuit. The slope compensation circuit generates a slope compensation signal based on a mode switching signal from the current cycle. The control loop, connected to both the slope compensation circuit and the switches, generates multiple switch control signals based on the slope compensation signal, a feedback voltage related to the output voltage, and a current sense signal related to the output current. This setup allows for precise control of the switches. The mode switching circuit, in turn, generates the mode switching signal for the next cycle, ensuring optimal operation of the buck-boost conversion circuit.
