| Abstract: | A DC/DC isolated power supply for the fire control system is developed by using the high performance current mode PWM chip UC3846.The input of the isolated power supply is driven by a DC 24 V battery.The push-pull forward topology is used in the power system to realize 24 V DC output.A patr form a detailed explanation of the new power system,experimental results were presented.It shows that the isolated power system can achieve superior performance with fast transient response,good stability, and strong isolation,which can satisfy the power needs of fire control systems. |
