1. These components directly affect the life of the power transformer.
Hi everyone, I’m Leah. Today, we’ll be discussing the life of power transformers and the key components that affect their longevity.
You may not know that the life of the power transformer actually follows the barrel effect, which means that the life of all components must meet the specified life to ensure the maximum service life of the power supply. So, what components should we pay special attention to?
- Capacitors: These components are very sensitive to temperature, and it can be said that the quality of capacitors largely determines the life of electrical appliances.
- MOSFETs (Metal-Oxide Semiconductor Field-Effect Transistors): These switching devices, under high-speed switching conditions, can withstand high voltage and current stress, and heat issues can also cause the devices to age faster.
- High Frequency Power Transformers: During the power transmission process, internal losses can cause heating, affecting the life of the transformer materials.
- Multilayer ceramic capacitors: The solder joints of surface-mounted ceramic capacitors are prone to problems, and it is recommended to avoid using multiple ceramic capacitors in parallel.
- Output Rectifier Diodes: Diodes bear two main electrical stresses – reverse voltage and forward current – and are also heat generating devices.
- Photocouplers: Current transfer ratio gradually decreases over time, which may damage the photocoupler.
In short, the value of a power transformer lies not only in the unit itself, but also in the level of process that ensures batch quality. Consumers need the safety and reliability of power transformers to reduce the production and maintenance costs of their products.
OKAdapter always strives to provide high quality, reliable and competitive power supplies to customers.
