How to delay the life of switching power supply

April 14, 2020

①Method one: pulse power or overcurrent limit

 Switching power adapters developed in new products, one by one pulse of super power, current limit is essential, this one by one pulse of super power or current limit, in practical applications is a very effective output overload protection method and Additional secondary current limiting protection is often used in this technology. In previous switches, the input current was monitored in real time. If the current exceeds the specified limit current, the pulse will be terminated. In a flyback Converter, the maximum current determines the power of the circuit. This type of protection circuit becomes a true power-limit protection circuit.


 ②Method 2: Ultra-power-off delay shutdown protection

 As a very effective output overload protection technology, ultra-power delayed shutdown protection technology has been widely used in domestic Power Adapter products. In the time-delay trip system, the requirement of short-term transient current is allowed. Only when the current stress exceeds the safe value for a long period of time, the power is turned off. The short-lived transient current will not endanger the reliability of the Power Supply, nor will it have a great impact on the cost of the power supply. Only long-term current requirements affect the cost and size of the circuit.
