Abstract: A switch controller for switching power supply is coupled to an auxiliary winding of the switching power supply through a detecting resistor. The switch controller provides a detecting current passing through the detecting resistor for keeping the voltage level of a detecting signal transmitted by the detecting resistor higher than a predetermined voltage. In this way, the switch controller can avoid the latch-up phenomenon caused by receiving the detecting signal of the negative voltage level. In addition, the switch controller can detect the magnitude of an input voltage of the switching power supply by means of the detecting current, and accordingly control the operation of the switching power supply.

The voltage converter comprises a feedback circuit, a transmission switch circuit, a voltage converting circuit, and a pre-bias circuit. The feedback circuit generates a feedback voltage signal according to the output voltage signal. The transmission switch circuit selectively transmits a converted voltage signal to the output port of the voltage converter in a normal mode or transmits the input voltage signal to the output port of the voltage converter in a pre-bias mode. The voltage converting circuit converts the input voltage signal into the converted voltage signal in the normal mode and references the feedback voltage signal and the reference voltage signal to adjust the output voltage signal in the normal mode. The pre-bias circuit controls a magnitude of a current passing through the transmission switch circuit.

Abstract: A high voltage charging circuit includes an activation control circuit, an inactivation control circuit and a power transistor. The activation control circuit is used for controlling an ON time period of the power transistor to enable the transformer to store excited-magnetic energy; the inactivation control circuit is used for controlling an OFF time period of the power transistor to make the transformer to release the excited-magnetic energy and use the excited-magnetic energy to charge the high voltage capacitor. Since the user can select a smaller Lp to keep constant the maximum value IP,max for the primary side current IP, the period tON can be made smaller as well, which means that a transformer 14 with a smaller volume can be utilized to reduce the entire size of the high voltage charging circuit.

Abstract: A high voltage charging circuit is provided with the ability of rapid charging. The circuit is composed of a turn-on control circuit, a turn-off control circuit and a transistor. The turn-on control circuit is adopted to set a turn-on time of a transistor such that the transformer may store magnetic energy, while the turn-off control circuit is used to set a turn-off time of the transistor such that the transformer may release the magnetic energy to charge a high voltage capacitor. Smaller inductance reduces the turn-on time of the power transistor owing to the maximum current of the primary side of the transformer. Therefore, a small-sized transformer may be employed to reduce the volume of the charging circuit with nonoccurrence of saturation.
