Apparatus for supplying power and medical device

A medical device, comprising:

• a detector and an apparatus for supplying power, wherein the apparatus comprises a power supply circuit and a processing unit
• the power supply circuit is connected with an electric energy input end of the processing unit, and the power supply circuit provides a first power supply for the processing unit;
• and
• a forward voltage output end of the processing unit provides a forward power supply, and a backward voltage output end of the processing end provides a negative power supply,
• wherein the processing unit includes a resonant circuit, a first switching frequency of the processing unit includes a resonant frequency of the resonant circuit, and the resonant frequency is outside an effective frequency range of a load of the apparatus for supplying power.

A high-voltage power supply, comprising:

• a booster circuit and a compensation circuit, wherein
• an input end of the booster circuit is connected with an input power supply, and an output end of the booster circuit is configured to provide output electrical energy;
• an input end of the compensation circuit is at least connected with the input end of the booster circuit;
• an output end of the compensation circuit is at least connected with a reference end of the booster circuit, and the compensation circuit is configured to adjust the output electrical power of the booster circuit according to a voltage of the input power supply.
