What Are the Protection Features of Switching Power Supplies?

Switching power supplies, as essential components of electronic devices, typically come with various protection features to ensure the safety of the equipment and users. Here are the common protection features of switching power supplies:

1. Over-Voltage Protection: Monitors the output voltage and automatically shuts down the output when the voltage exceeds the set range to prevent damage to the equipment and circuits.
2. Over-Current Protection: Monitors the output current and automatically shuts down the output when the current exceeds the rated value to prevent circuit overload and protect the equipment.
3. Short-Circuit Protection: Immediately cuts off the power output when a short circuit occurs at the output terminal to prevent damage to the power supply and devices.
4. Overload Protection: Automatically reduces the output current or shuts down the output when the power supply exceeds the rated load to prevent overheating and damage.
5. Over-Temperature Protection: Monitors the temperature of the power supply and automatically reduces power or shuts down the output when the temperature exceeds the safe range to prevent overheating and safety issues.
6. Under-Voltage Protection: Automatically shuts down the output when the input voltage falls below a certain level to prevent unstable operation of the equipment under low voltage conditions.
7. Soft-Start/Soft-Stop: Reduces the impact of switching power supplies on circuits and devices during startup and shutdown, extending the device’s lifespan.
8. EMI Filtering: Reduces electromagnetic interference to protect devices from external electromagnetic interference and ensure stable operation.
