The voltage output by the direct-current power supply is linearly and continuously adjustable, and the linearity and the stability of the voltage are superior to those of a conventional high-voltage direct-current power supply; and the high-frequency low-voltage transformer is adopted and conventional devices are used, so the voltage class required by the insulation grade is lower, and the safety is better. The power supply is convenientto maintain, saves the cost, is easy to replace when the fault appears, and cannot produce the harmonic wave which affects electric networks.

Description

Technical field [0001] The invention relates to a high-voltage power supply, in particular to a linear adjustable high-voltage direct-current power supply for electromagnetic biological effects. Background technique [0002] The electromagnetic biological effect of animals and plants is one of the important technical means to directly promote agricultural production and improve product quality. Its research requires a large-scale and high-precision DC electric field. Technical issues such as high cost. For example, although the numerical control power supply used is easy to operate, its output high voltage is determined by its own numerical control characteristics to be continuously adjustable in steps rather than linearly. A 15kV digital control power supply has a minimum adjustment accuracy of 60V, which cannot meet the demand in electromagnetic biological effects that require high-precision voltage output.
