感应加热电源数字移相触发器设计

The design of digital phase shift trigger of the induction heating power supply

用数字触发器的设计思想设计其硬件结构并对软件算法进行了改进。改进后的数字移相触发器简单可靠,产生脉冲的对称性好,抗干扰能力强,能够保证捕获到每一个换相区并及时触发。

In this paper,the phase shift trigger is referred and improved. The system is simple 、reliable,has good performan of semmetry and against interference.It can assure capture every phase interval and trigger immediately.
