Inverter Split-Phase Output Terminal Description
Tips: Service Life of Components of Power Inverter
Inverter belongs to switching power supply in a broad sense, so its components can be basically divided into resistors, capacitors, diodes, power devices (IGBT or MOS), inductors and transformers, current sensors, IC, optocouplers, relays and so on.
The service life of resistors, patch capacitors and ceramic capacitors can generally reach more than 20 years. When designing inductors and transformers, as long as they do not exceed the material temperature, they are theoretically considered to be able to work for a long time without failure; low-power diodes, transistors can basically work for more than 100,000 hours; for relays, their mechanical life is basically more than 1,000,000 times and electrical life is more than 10,000 times. As long as the design specifications are met, the life of power device IGBT or MOS is generally not considered. Fans and fuses of power inverters are vulnerable components, which will not affect the life of the inverters, but can be replaced in time if they are damaged. The service life of thin film capacitors is more than 100,000 hours; the lifespan of electrolytic capacitors is generally 2000-3000 hour at 105℃, and the longer one is only 5000-6000 hours, but with the temperature decreasing by 10℃, the lifespan turns over. Times. So in the power inverters, the shortest part of the device is the life of the electrolytic capacitor.
