technical field [0001] The invention belongs to the technical field of high-voltage power supplies, and in particular relates to a small-sized high-voltage power supply module capable of rapid discharge and continuous voltage regulation. Background technique [0002] The high-voltage circuit of the current small high-voltage power supply often adopts the mains connection, and the transformer boosts the double voltage rectification method to perform boost rectification. During voltage regulation, when the output is a capacitive load, the voltage doubling rectification method often used has the defect of difficult discharge, and the discharge cycle required for the load to discharge and step down with parallel resistors is longer. [0003] Where the size and weight are limited, the power supply generally uses a switching power supply instead of a linear power supply. Linear power supplies are bulky and bulky, and are generally not suitable for occasions that are light in weig...
