Abstract
The invention provides a boost circuit including a first capacitor, a transformer, a sensing resistor and a second capacitor. The transformer has a boost side coil with its one end connected in series with the first capacitor. The sensing resistor is connected in series with the other end of the boost side coil of the transformer, and one end of the second capacitor is connected in parallel with the transformer. Also, the invention provides a power supply converter including a boost circuit and a detection circuit. The boost circuit is used to produce a voltage and output a detection signal to detect the occurrence of a spark. The detection circuit is electrically connected with the boost circuit and is used to receive the detection signal output by the boost circuit. When the detection circuit detects the detection signal contains an inrush signal, it determines that a spark is occurring within the boost circuit and outputs a control signal according to the inrush signal.
