Abstract (en)

[origin: WO2019018148A1] A high voltage generation circuit is disclosed, which includes a battery for providing a first direct current voltage, a first inductance connected in series with the battery, a power switch and a voltage multiplier. The power switch is configured for converting the first direct current voltage to a pulse voltage. The voltage multiplier is configured for multiplying the pulse voltage to a second direct current voltage. The second direct current voltage is higher than the first direct current voltage. The voltage multiplier includes super capacitors which are connected in series. A high voltage generation method is also disclosed.
