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.
