Zero-crossing trigger of SCR is a common problem in the practical application of SCR, especially in three-phrase systems. This paper presents a new circuit for generating three-phrase synchronous zero-crossing pulse. It can provide 6 paths signals each with 60 degree width. This circuit ha an ingenious conception and is easy to be realized. It also can block pulses while circuit breakdown.
