多绕阻输出的电源需要对输出作过电压和低电压的保护,下面介绍的电路就是达到此目的简单作法。设定过压/低压保护额定值的比较电压输出以OR逻辑门接在一起,然后经由齐纳二极管送到固态继电器(SSR)的输入端。一块LM324 IC,可供四个电压保护电路使用。
Multi-winding output power needs to be over-voltage and low-voltage output protection, the circuit described below is a simple approach to achieve this purpose. Setting Overvoltage / Undervoltage Protection Ratings The voltage outputs are OR logic gates and are then fed via Zener diodes to the SSR inputs. One LM324 IC for four voltage protection circuits.
