The invention relates to a programmable
nanosecond double-pulse integrated power supply which comprises a
voltage regulating and rectification circuit and a
chopper circuit, wherein the input end of the
voltage regulating and rectification circuit is connected with industrial frequency
alternating current, the output end of the
voltage regulating and rectification circuit is connected with the input end of the
chopper circuit and the output end of the
chopper circuit is the output end of the power supply; the output end of the chopper circuit is respectively connected with a tool
electrode and a
processing workpiece; the chopper circuit is connected with a high-frequency
control circuit which outputs a
control signal to control the output of the chopper circuit so as to control the current direction in the tool
electrode and the
processing workpiece, and positive and negative pulses as required can be obtained between the tool
electrode and the workpiece; the high-frequency
control circuit comprises a high-frequency
logic control circuit and an amplifying circuit, wherein the high-frequency
logic control circuit outputs a high-frequency
logic control signal which is amplified by the amplifying circuit to obtain a
control signal for controlling the chopper circuit. Compared with prior art, the programmable
nanosecond double-pulse integrated power supply of the invention has the advantages of wide pulse-width adjustable range, narrow minimum pulse width and high
pulse frequency, is convenient to be set with parameters and easy to access to a micro
electrochemical machining computer
numerical control system and can realize the online real-time adjustment of power supply parameters.
