Problems solved by technology

For high-frequency pulses with a frequency of about 10,000 Hz, the energy consumption makes the high-voltage transformer unable to work normally, and under the condition of a certain inductance, the high frequency will seriously distort the output pulse waveform, so that the required pulse waveform cannot be obtained. meet production requirements
[0005] The prior art also proposes a high-frequency high-voltage pulse power supply composed of a DC high-voltage power supply, a voltage doubler rectifier, a signal source, and a voltage-stabilizing transistor. However, the cost is high on the one hand, and the current is small on the other hand. About 1mA~5mA, which cannot meet the requirements of electric dehydration with large current requirements

Embodiment 1

[0046] Embodiment 1: Control process of DC power supply with output voltage of 8000 volts

[0047] Assuming that the output of each filter circuit is an 800-volt DC power supply, when it is necessary to output a DC power supply with a voltage of 8,000 volts, the computer controller 6 sends high-voltage power to 10 high-frequency pulse generating circuits 41, 42...410 through the drive unit 10 At the same time, the computer controller 6 monitors whether all the signals are consistent with the commands through the measuring unit 11 and the pulse current detection element. When there is no need to output DC power, the computer controller 6 sends zero-level driving signals to all high-frequency pulse generating circuits.

[0048] In fact, the 10 high-frequency pulse generating circuits are not limited to the first to tenth ones, the computer controller 6 can send high levels to any 10 high-frequency pulse generating circuits, and the same effect can also be achieved.

Embodiment 2

[0049] Embodiment 2: Control process of a high-voltage and high-frequency pulse power supply with output voltage of 4000 volts, pulse width of 0.05 milliseconds, and period of 0.1 milliseconds

[0050] Assuming that the output of each filter circuit is an 800-volt DC power supply, when the designed high-voltage and high-frequency pulse power supply is needed, the computer controller 6 sends a pulse width of 0.05 milliseconds to any five high-frequency pulse generating circuits through the drive unit 10. The pulse driving signal is 0.1 millisecond, and at the same time send zero-level driving signals to the remaining N-5 high-frequency pulse generating circuits, and the computer controller 6 monitors whether all signals are consistent with the commands. When it is not necessary to output the designed pulse power supply, the computer controller 6 sends a zero-level driving signal to all high-frequency pulse generating circuits.

[0051] Embodiment 3: The control process of a high-voltage high-frequency pulse power supply with a voltage of 4000 volts, a pulse width of 0.05 milliseconds, and a period of 0.1 milliseconds and a DC hybrid power supply of 8000 volts

[0052] It can be realized by combining the above two situations of the first embodiment and the second embodiment.
