Abstract :
Valley V2 control technique for switching converters is proposed in this paper. By utilizing output voltage ripple as pulse-width modulation ramp and valley voltage of output voltage ripple as additional control variable, valley V2 control technique provides faster load transient response than conventional current-mode control techniques. Steady-state and transient performances of switching converters with valley V2 control, peak V2 control, and current-mode control are compared and verified by experimental results.
