In some special application scenarios, the power outage holding time of conventional AC-DC switching power supplies cannot meet the requirements, and switching power supplies with ultra long power outage holding time are very rare in the market. To meet the needs of these special application scenarios, this article theoretically analyzes the factors that determine the power outage holding time and proposes a simple method to increase the power outage holding time through peripheral circuits.

The KJ3204X1-BA1 12P3275X032 KJ4001X1-CJ1 VE4002S1T2B5 switching power supply has an important technical parameter – the power-off holding time, which refers to the time difference ST from AC power-off to the output voltage falling outside the accuracy range (usually -2%), as shown in Figure 1. Simply put, it means how long the output of a switching power supply can last without input.

In many cases, after detecting an AC power outage, the system needs to save and transmit data, set the status of the actuator, and so on. Therefore, after the power failure of KJ3204X1-BA1 12P3275X032 KJ4001X1-CJ1 VE4002S1T2B5, the switch power supply needs to be able to continuously provide power to the system for a period of time to ensure reliable shutdown of the system. In addition, in systems with UPS, during the process of switching from mains power to UPS power supply, it is also necessary for the switching power supply to maintain normal output.
