Research on PV MPPT Technology Based on Two-Phase Synchronous Staggered Buck

To maximize the utilization of space solar array energy, a PV MPPT method based on two-phase synchronous staggered Buck is proposed in this paper. MPPT is the key technology of PV power generation systems. The MPPT fuzzy control method can realize accurate and fast maximum power tracking. Using a two-phase synchronous staggered Buck circuit can reduce the ripple of output voltage, reduce the device power loss, and improve the power output efficiency, and provide a solution for the lightweight design of a space power system. Finally, the simulation model is built with MATLAB, and the maximum power tracking accuracy of 99.6% is obtained, and the maximum power tracking is achieved by 4.2 ms, which verifies the feasibility of the method.
