Abstract

The invention discloses a high-voltage power supply using a television high-voltage package as a boosting device. A 220V mains supply is connected with a television high-voltage package through a rectifier circuit and a filter circuit in turn. The television high-voltage package is used as a boosting device of a high-voltage regulated power supply. The output voltage of the television high-voltagepackage is fed back to one input end of a comparator, and a given voltage is input to the other input end of the comparator. The output end of the comparator is connected with a control circuit. A PWM square wave obtained by comparing the output voltage of the control circuit with a sawtooth wave is used to drive the television high-voltage package to be boosted and get a target voltage. By usinga television high-voltage package as a boosting device, a 220V AC mains supply provided by the State Grid can be converted into a high-voltage regulated power supply needed by equipment represented by an ion accelerator, continuous adjustable voltage of 0-15kV can be realized, the voltage output is stable, and the high-voltage power supply is safe and reliable.

Description

technical field [0001] The invention relates to the field of high-voltage power supplies, in particular to a high-voltage power supply using a television high-voltage pack as a booster. Background technique [0002] In today's power supply market, the majority are switching power supplies and linear power supplies. The switching frequency of the switching power supply can reach 10kHz, the volume is small, the loss is small, the linear power supply can be easily adjusted from 0V, and the electromagnetic interference is small. However, the duty cycle of most switching power supply switching tubes is difficult to adjust to close to 0, so it is difficult to adjust the power supply voltage from 0; on the other hand, the linear power supply is bulky and has a large loss. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems by providing a high-voltage power supply using a high-voltage pack of a TV set as a boosting devic...
