Design of Micro Energy Pulse Power Supply for Multi Electrode Synchronous Micro-EDM
IOP Conference Series: Materials Science and Engineering
In order to solve the problem of low efficiency of micro-EDM, a micro energy pulse power supply for multi electrode synchronous micro-EDM was designed. The power supply outputs high-frequency PWM signals from the processor STM32F103RCT6, which processed by the discharge control loop can drive the high power field effect transistor to control the capacitance charge-discharge. Capacitance quantitative energy storage and pulse width adjustment of micro energy pulse are realized by changing thedoi:10.1088/1757-899x/452/3/032069 fatcat:iligei5dync5bpzfvpdc7nur3m
