An inverter, it has to be an inverter to be called that. It is directly different from the transformer, that is to say, the inverter can achieve DC input, and then output AC, the working principle is the same as the switching power supply, but the oscillation frequency is within a certain range, for example, this frequency is 50 Hz, the output is AC 50 Hz. An inverter is a device that changes its frequency. UPS inverter is a device that provides backup power to electronic equipment. It is mainly used to provide uninterrupted power supply to some equipment which requires high stability of power supply. In this article, we will introduce how to choose ups inverter.
