Abstract：In order to achieve the highest energy efficiency of the equilibrium system, an improved parameter optimization method for equilibrium circuit is proposed. The important parameters in the balanced circuit, including the duty ratio of PWM wave and the cycle T, are optimized near the initial selected values. The simulation model of the optimization method is designed by Simulink. The simulation results show that the optimal duty cycle of the maximum energy efficiency per unit period is 0.52 and the optimal period is 0.1s.
