specific Embodiment approach 1
[0084] Specific implementation method 1. Refer to Figures 1 to 10 Embodiments will be described. A multi-mode adjustment method based on a multi-mode adaptive pulse power supply described in this embodiment, the multi-mode adjustment method is realized based on a multi-mode adaptive pulse power supply of multi-layer material EDM,
[0085] Multi-mode adaptive pulse power supply for multi-layer material EDM, which includes industrial computer, discharge gap, drive amplifier module 1, discharge main circuit 2, sampling module 3, main controller 4, voltage divider chopper sampling circuit and eddy current sensor ;
[0086] The driving amplifier module 1 includes 8 low-voltage loop driving circuits 1-1, 1 high-voltage loop driving circuit 1-2 and 1 negative pulse loop driving circuit 1-3; low-voltage loop driving circuit 1-1, high-voltage loop driving circuit 1- 2 and the negative pulse loop driving circuit 1-3 are independently powered by DC power supply, and do not share the g...

[0148] Specific embodiment two, refer to Figure 4 Note that in this embodiment, in the third step, the main controller 4 performs the mode selection process according to the discharge parameter serial data, the discharge time sampling signal, the abnormal discharge sampling signal, and the material type sampling signal. The mode selection process is as follows :
[0149] The serial port receiving module 4-1 receives the discharge parameter serial data required for multi-layer material EDM sent by the industrial computer, converts it into discharge parameter parallel data according to the corresponding logical structure, and sends it to the parameter adjustment module 4-3;
[0150] The material type discrimination module 4-2 receives the material type sampling signal sent by the material type sampling circuit 3-3 and the low-voltage loop PWM signal output by the PWM generation module 4-5, and analyzes the material according to the material type sampling signal and the low-volt...
specific Embodiment approach 3
[0158] Specific implementation three, refer to Figure 8 Illustrating this embodiment, the mode selection module 4-4 performs mode selection according to the pulse mode signal, and outputs a high-voltage pulse signal, a negative pulse signal, and a 5-way mode enable signal to the PWM generation module 4-5; the 5-way mode The enable signals are enable signal 1, enable signal 2, enable signal 3, enable signal 4 and enable signal 5, which are used to control the operation and stop of the PWM generation modules 4-5. The mode selection method is as follows:
[0159] Pulse mode signal input, divided into two channels after input, one channel judges the last 3-bit data of the pulse mode signal, and the other channel outputs the first 5-bit data of the pulse mode signal;
[0160] When judging the last 3-bit data of the pulse mode signal, if it is "001", the voltage is enabled to output '1', the other mode enable output is '0', and the other mode enable output '0' is returned to contin...
