In the process of new product development and design of switching power adapters China, engineers usually add some protection measures to the designed new products, so as to avoid short circuit or component damage of switching power adapters China during use, shortening its working life. In today's article, we will share with you the protective measures that can prolong the service life of switching power adapters China. Let's take a look.

Method 1: Pulse-by-pulse overpower or overcurrent limiting
In the process of new product development of switching power adapters China, pulse-by-pulse over-power and over-current limitation is essential, and this kind of pulse-by-pulse over-power or over-current limitation is a very effective output overload in practical applications. protection method, which is often used in additional secondary current limiting protection.
Method 2: Over-power time-delay shutdown protection
As a very effective output overload protection technology, the ultra-power time-delay shutdown protection has been widely popularized in the switching power adapter China produced in China. In time-delay trip-type systems, short-term transient current requirements are tolerated, and the power supply is only turned off when the current stress exceeds a safe value for an extended period of time. The provision of short transient currents will not compromise the reliability of the power supply, nor will it significantly affect the cost of the power supply. Only the requirement of long-term continuous current will affect the cost and size of the circuit.
