Abstract： Based on the current reversible chopper circuit, the Buck-Boost converter is constructed by sliding mode control method, and a battery simulator with two-way current flow in topological structure is implemented to simulate the charging and discharging process of the battery. Buck circuit is formed when the capacitor voltage is higher than the battery voltage, and Boost circuit is formed when the capacitor voltage is lower than the battery voltage. Compared with the traditional Pi Control, the sliding mode control has better robustness and dynamic performance when the load fluctuates than the PI Control. On the basis of theoretical analysis, the experimental results are obtained by simulation software.
