Abstract

The invention discloses a high-voltage generating circuit, which includes a battery for providing a first DC voltage, a first inductor connected in series with the battery, a power switch and a voltage multiplier. The power switch is configured to convert the first DC voltage into a pulsed voltage. The voltage multiplier is configured to multiply the pulsed voltage to a second DC voltage. The second DC voltage is higher than the first DC voltage. The voltage doubler consists of a number of supercapacitors connected in series. The invention also discloses a method for generating high pressure.

Description

technical field [0001] The present invention generally relates to the field of voltage generation, in particular to a high-voltage generating circuit and a high-voltage power generation method. Background technique [0002] In many power generation systems, such as underground power generation systems, it is necessary to provide a load with a high direct current (DirectCurrent, DC) voltage. Therefore, such power generation systems generally require a high voltage generating circuit to supply a desired voltage to a load. [0003] Conventional high voltage generating circuits usually include a voltage multiplier to multiply to obtain a higher voltage. The voltage doubler consists of a number of supercapacitors connected in series. However, due to the difference of the supercapacitors, the voltage of the supercapacitors will be unbalanced during the operation of the high voltage generating circuit. [0004] Therefore, in view of this, the demand for how to realize cell balan...
