A method of and device for reducing power loss in a voltage conversion circuit. The voltage conversion circuit comprises a main power circuit and a switchable auxiliary circuit, which comprises a first and a second winding circuits. A switch controls the use of the first winding circuit, the second winding circuit, or both to reduce power lose during the voltage conversion.

Switchable auxiliary supply circuit

The present application discloses a method and apparatus for detecting liquid level with probe, and the method comprising steps of: (A) acquiring a capacitance value of the probe; (B) generating an analog signal corresponding to the acquired capacitance value; (C) converting the generated analog signal into discrete signals at a predetermined sampling interval; (D) increasing or decreasing a counting value according to an amplitude of each the discrete signals, and outputting a liquid level contacting indication signal when the counting value reaches a predetermined counting threshold; and (E) controlling a movement of the probe according to the output liquid level contacting indication signal.
