A flying capacitor type boost circuit control method, medium, device and system

Abstract

This application discloses a control method, medium, device, and system for a flying capacitor type Boost circuit. The method includes the following steps: Based on the relationship between the original MPPT disturbance direction, duty cycle range, and voltage deviation of the flying capacitor, a collaborative decision matrix is ​​obtained to determine the final MPPT disturbance direction; the electrical parameters of the flying capacitor type Boost circuit are collected, and relevant parameters are calculated and substituted into the collaborative decision matrix for querying to determine the final MPPT disturbance direction; the duty cycle of the flying capacitor type Boost circuit is updated according to the obtained final MPPT disturbance direction. The medium, device, and system are all used to implement the above method. The beneficial effects of this application are: Compared with the traditional dual-loop architecture, this application adopts single-loop collaborative control, requiring no additional fine-tuning, fundamentally eliminating the disturbance of the equalizing control loop to the MPPT, and ensuring that the actual operating point is always located at the true maximum power point.
