Abstract
The invention discloses a micro-fine nanosecond-level pulse power device. A first output end of a pulse generator in the device is connected with an input end of a low-voltage isolation driving module, an output end of the low-voltage isolation driving module is connected with a first input end of an amplification module, a constant-voltage power supply is connected with a power end of the amplification module, an output pulse signal of the pulse generator is subjected to be first-level low-voltage driving acceleration amplification by the low-voltage isolation driving module and then is subjected to second-level high-voltage energy amplification by the amplification module so as to provide energy for a discharging processing region, a second output end of the pulse generator is connectedwith a control end of a power adjustment output module, an output end of the power adjustment output module is connected with a second input end of the amplification module, an output control signal of a second output end of the pulse generator is subjected to photoelectric coupling by the power adjustment module and then an output of the amplification module is adjusted. By the micro-fine nanosecond-level pulse power device, the stability of the pulse power supply can be improved, the line cutting processing smoothness is further improved, and the part processing quality is improved.
Description
technical field [0001] The invention relates to the field of pulse power supply, in particular to a micro-precision nanosecond pulse power supply device. Background technique [0002] With the development and improvement of the technical level of all walks of life, users have further improved the surface quality and smoothness of the parts manufactured by electric machine tools. In modern power electronics, the new micro-energy controllable micro-precision and nanosecond pulse power supply for wire-cut electric discharge machining provides a technical guarantee for high-quality and expanded processing fields. In practical applications, there are many factors that affect the process index of micro-precision wire-cut electric discharge machining, and the pulse power supply is the key factor, which needs to meet the discharge energy of less than 35J during micro-energy processing. In the micro-finishing state, the uneven discharge energy will erode the product, resulting in a ...
