Technical FAQs 4

What is the difference between low frequency and high frequency inverters?

In fact, low frequency inverters can operate at the peak power level which is up to 200% of their nominal power level for several seconds, while high-frequency inverters can operate at 150% power level for a small fraction of a second.

What are the advantages of high frequency inverters?

Volume and weight: Since high frequency inverters use high-frequency switching technology and compact circuit design, their size and weight are usually much smaller than power frequency inverters. This gives high frequency inverters significant advantages in mobile power supplies, aerospace, electric vehicles, and other fields.

Why are frequency drive inverters more efficient?

Efficiency and energy consumption: Because frequency drive inverters use high-frequency switching technology, their switching losses and iron losses are relatively small, so their efficiency is usually higher than that of power frequency inverters.

What internal frequency do inverters operate at?

What internal frequency the inverter circuits operate at – low frequency or high frequency (not to be confused with AC power output frequency which is a standard 50Hz for our inverters). Low-frequency inverters have the advantage over high-frequency inverters in two fields: peak power capacity, and reliability.
