1. DC-to-DC converter comprisesInductor and the electronic switch that is used for supplying to inductor DC input voitage on conducting phase period ground, wherein the inductor current by inductor increases,Be used to produce and represent the testing circuit of the detection signal of partial inductance device electric current at least,Be used to produce the reference level circuit of the reference level of the output voltage that depends on DC-to-DC converter and the difference between the predetermined reference value,Be used to produce the average correction signal of difference between expression detection signal and the reference level average circuit andBe used to depend on the controller of the duty ratio of relatively adjusting conducting phase of detection signal and current threshold level, wherein current threshold level depends on reference level and average correction signal.
