开关电源和普通变压器电源(又称线性电源)有什么区别?优势在哪里?
1. 工作原理差异：开关电源 operate in a switching mode，alternating between on and off states，while 普通变压器电源，也称为线性电源，operates in a linear mode，where the voltage is regulated by adjusting the conductance of the components to share the voltage or current.2. 效率对比：开关电源 features high efficiency due to the minimal losses associated with switching components. In contrast, 线性电源 dissipates more energy as heat during regulation.
3. 噪声差异：开关电源 generates significant electromagnetic interference (EMI) both internally and externally due to its switching action. On the other hand, 线性电源 produces less noise as it relies on a more stable and continuous regulation process.
