Abstract :
In order to inhibit the low-frequency oscillation phenomenon exists in traditional pulse train (PT) controlled switching converters operating in continuous conduction mode (CCM), constant on-time semi-hysteresis pulse train (SHPT) control technique of switching converters is proposed and SHPT controlled CCM buck converter is studied in this paper. Experimental results show that SHPT control technique effectively inhibits the low-frequency oscillation phenomenon of PT controlled switching converters operating in CCM.
