Abstract
The utility model provides a precise voltage-regulating high-voltage power supply device. W2 is adjusted within the reference voltage V6. The pulse width and pulse frequency of a high-frequency impulse oscillation circuit H3 are synchronously controlled by a comparator A2 and a comparator A3, the pulse width and the pulse frequency are caused to change synchronously. DC-AC inverse transformation is finished by B1 and H4. B2 and H5 are used to increase the voltage, commutate, and filter the wave. The voltage can be continuously adjusted within a big scope of 0-40 KV DC. The voltage and current closed loop/feedback loop causes a stable DC high-voltage and constant-current output. The utility model is smart in the technical, small in the volume, light in the weight without the noise.

Three, Fa Ming purpose
The purpose of this utility model is to transfer wide realization high direct voltage output 0V to play accent, 0-40KV by synchronous tracking high frequency to adjust continuously on a large scale; By close-loop feedback control, realize accurate voltage stabilizing and constant current output.
The purpose of this utility model is achieved like this: adjust W2 in reference voltage V 6 scopes, by voltage comparator A2 and frequency of oscillation controller A3 difference Synchronization Control high-frequency impulse width and frequency, make 5, the 6 ends pulse that output frequency, width change synchronously between low frequency and narrow pulse and high frequency broad pulse state of high-frequency oscillating circuits H3, finish the DC-AC inversion through B1, H4, finish by B2, H5 boost, rectification, filtering be from the 4 ends output 0-40KV high direct voltage of H5.R1 and R2 series connection are carried out dividing potential drop to the high direct voltage of the 4 ends output of H5, the voltage that obtains is sent into 1 end of A2 after the A4 impedance conversion, pulse duration by A2 control H3 output forms the closed feedback loop of output voltage, thereby stablizes the 4 ends output high tension voltage of H5; The electric current that flows through R3 is carried out voltage sample, and send 2 ends of A1 and 1 terminal voltage to compare, the pulse duration of control H3 output, form becomes the closed feedback loop of output current, makes the current constant of the 4 ends output of H5.
The high voltage source that the utility model provides is with technical scheme cleverly, reached the effect that 0-40KV adjusts voltage and accurate voltage stabilizing, constant current output on a large scale continuously.Has little, in light weight, the noiseless advantage of volume.
