What is DC/AC inversion technology?

DC/AC inversion technology is of vital importance for industrial applications, including electrical vehicles and renewable energy systems, which require a large number of inverters. In recent years, inversion technology has developed rapidly, with new topologies improving the power factor and increasing power efficiency.

What is an inverter-driven compressor?

An inverter-driven compressor has the ability to increase or decrease its rotational speed thereby enabling inverter air conditioners to regulate their cooling capacity based on the needs. Often, people who own inverter air conditioners tell you that inverter air conditioners can sometimes be noisy, especially during startup.
