Application: Adaptive ramp time modulation (Patent ID: US20240213967A1)
The patent filed by Power Integrations Inc. describes a controller for a power converter that includes a drive circuit and an adaptive current limit generator. The drive circuit receives a request signal indicating the power demand of the output and generates a drive signal to control the power switch accordingly. The adaptive current limit generator generates a current limit signal that varies based on the switching frequency of the power switch, turning off the switch when the current sense signal reaches the limit. By adjusting the upper threshold of the current limit signal based on the switching frequency, the controller can regulate the power converter's operation between different modes to optimize power delivery.
The controller's adaptive current limit generator includes an upper threshold generator that adjusts the current limit range based on the switching frequency and a ramp generator that generates the current limit signal. The upper threshold varies between two values depending on the frequency threshold, controlling the power converter's operation modes. The drive circuit, on the other hand, includes a comparator and a latch to generate the drive signal in response to the request signal and current limit signal. Overall, the controller's design allows for efficient energy transfer and power delivery by dynamically adjusting the current limit based on the switching frequency of the power switch, optimizing the power converter's performance.
