Several factors affecting the life of military power supplies

Military power supplyThe lifespan of a power supply is just as unpredictable as a human being, only the average power supply lifespan in big data. So how can military power supplies extend the service life?

To reduce the occurrence of power module failures to ensure its long-term stable operation, it is necessary to control the two links (R&D and production) in the life cycle of military power supplies.

1. Power supply research and development: It is necessary to ensure that the performance of the power supply meets the requirements of the specifications and the performance indicators during the normal use cycle of the power supply.

2. Power production: This type of product has high requirements for production process and process control, and requires high-quality equipment and management to achieve the expected quality and ensure the life of the power module.

The components of the military power supply will also affect his life:

1. Electrolytic capacitor

Electrolytic capacitors are sensitive to temperature

For more sensitive components, it can even be said that the life of the electrolytic capacitor is the life of the power supply, because the life of the circuit components is shorter. The main factors affecting the life of electrolytic capacitors are ambient temperature and ripple current. The heat caused by both will be manifested through temperature rise, so temperature rise is a factor that has a greater impact on the working life of electrolytic capacitors.

2. Power chip IC

Because it is a core component, it is generally recommended to choose a big brand to ensure performance and craftsmanship, but it needs to be balanced with the cost.

3. Rectifier diode

The diode is mainly subjected to two major electrical stresses, including reverse withstand voltage and forward current. Since the diode is a heating device, in order to ensure its service life, it is recommended to flow out enough margin in the design.

4. High frequency transformer

During the energy transmission of high-frequency transformers, internal losses will cause heat generation and affect the life of the transformer. Common causes of transformer failure include insulation breakdown, winding burnt, and copper wire breakage.

The above are the major factors that affect the life of military power supplies. Learn a little about power modules every day and life will become better!
