What is a power supply inverter and how it works?

- Oct 25, 2019-

The power supply inverter, also known as the power converter, converts low-voltage DC (DC12v DC24V and other DC) into 220V of the required commercial AC. But unlike the transformer, the inverter can achieve DC input AC output, but its working principle is the same as our switching power supply.

UPS uninterruptible power supply It is a power supply inverter. In the case of mains power failure, its multiple DC batteries (DC12V) are connected in series to the UPS to send DC power, and then the UPS output AC 220V to the important control equipment.

The main points of the UPS power supply inverter: 1. The UPS power supply inverter is within the allowable input DC voltage (general DC192 or DC240v). At this time, the UPS power supply can output the rated voltage value (AC220v), when the UPS is stable. , its voltage fluctuation range will not exceed the rated value ± 3% or ± 5%. 2. Several points of output voltage imbalance, output voltage waveform distortion, rated output frequency, load power factor, rated output current, rated output efficiency, protection, starting characteristics and noise of UPS power supply inverter

The use of the power supply inverter in the vehicle system, as long as there is 12V power supply can achieve 220V AC, convenient. However, in the industry, the controller can not be powered off in some important automatic control situations. Therefore, multiple DC 12v levels are used to give the UPS. When the mains power-off controller works, it avoids the loss of some important data.
