Patent ID: 10910941

Abstract:
The present invention provides an AC/DC converter comprises an input for receiving a rectified AC input signal (Vin), an output for providing a controlled output signal (Vout) to a load (7), a switched mode power converter for transforming the AC input signal (Vin) into the controlled output signal (Vout), wherein the switched mode power converter has an input for receiving a start-up voltage (Vstart) for changing a stand-by mode of the switched mode power converter into an operating mode of the switched mode power converter, a control circuit (5) for receiving a control signal (Vctl), a kick-start power supply (6) for receiving a switch-on signal (Von) to supply the start-up voltage (Vstart) being larger than a power supply voltage (Vsup), an auxiliary power supply (4) for supplying the power supply voltage (Vsup) to the control circuit (5) and the kick-start power supply (6), wherein the control circuit (5) is arranged for activating the switch-on signal (Von) to activate the kick-start power supply (6) for turning the switched mode power converter from the stand-by mode into the operating mode.
