摘要
介绍了一种单端反激式DC—DC变换电路。以固定频率脉宽调制控制集成TL494为核心,设计制作了一款升压型开关稳压电源,并对该电源进行了实验测试,其测试结果表明:该开关稳压电源具有输入电压范围宽、高负载稳定度、效率高、工作可靠等优点。
This paper introduces a single-end fly-back DC-DC inverter circuit. The boost switching power supply is based on TL494 with the characteristic of PWM of constant frequency. The design of the power supply is verified by testing.
