【摘要】 提出了电火花加工脉冲电源逆变式结构的一种控制策略,阐明了其实现方法和控制原理。在控制效果上实现了对脉冲电源主要参数的控制:采用专用的PWM波发生器UC3825A实现加工电压的自适应控制;选用双精度单稳态触发器实现脉冲宽度和脉冲间隔的时序控制;同时通过对PWM波的封锁控制实现过流保护。更多还原

【Abstract】 A method for controlling an inverting EDM pulse generator was introduced and illustrated the designing way and controlling principle.This project controlled the main parameters of inverting EDM pulse generator: used the special PWM generator UC3825A to realize voltage adaptive controlling;used dual precision monostable to control the time of pulse width and pulse interval,simultaneity,rush current and short circuit protection were carried out via cutting off PWM wave.更多还原
