Abstract This paper proposed a hysteresis control strategy based on capacitor charge balance, the operation theory is described with a Buck converter as an example. Firstly, the small signal model is derived by the state-space averaging method. Based on this, the influence of controller parameters on system is discussed, and frequency-domain simulation is performed and analysed by contrast on traditional voltage controlled and propoede hysteresis controlled Buck converter, finally, the experimental result are given. The simulation and experimental results have shown that the proposed control strategy has faster transient response and better anti-interference ability than traditional voltage controlled for Buck converter.
