Abstract The three-level buck converter can reduce the voltage stress of switch,double the effective switching frequency and decrease the size of filter. The small-signal model of flying capacitor voltage control and the constant frequency sliding mode controlled of output voltage control are established by the method of voltage decoupling control strategy. Then the compensation networks are designed. At last,the simulation results show the correctness of theoretical analysis and the effectiveness of control strategy.
