Abstract
This paper introduces an improved design for a safe AND gate,based on PWM control chip(UC3844),and features high-precision outputs and load adjustments.The working principle and implementation scheme of the circuit are discussed in detail,and a voltage feedback network is adopted,which is composed of an optocoupler(EL3H7A)and an adjustable precision shunt regulator(TL431A).The performance of this safe AND gate is excellent,with advantages that include a simple structure,good voltage stabilization,a high load adjustment rate,and high value in production and application.关键词
