What does inverter power supply mean? A power supply that changes from direct current to alternating current is called an inverter power supply. Typically, thyristor circuits are used to convert direct current into alternating current. This reverse process corresponding to rectification is defined as inversion. What is the meaning of inverter power supply, for example: an electric locomotive using thyristors, when braking downhill using a DC motor as a generator, the potential energy of the locomotive is converted into electrical energy and then returned to the AC grid. Another example is a DC motor in operation. To make it brake quickly, you can also run the motor as a generator to convert the motor's kinetic energy into electrical energy and then send it back to the grid.

        Grid-tied inverters are multifunctional devices developed using photovoltaic power generation. In addition to converting DC power from photovoltaic panels into AC power, it also has the function of synchronizing with the grid. This kind of inverter will have a certain delay after being powered on. During this delay, the inverter will actively collect the frequency, amplitude, phase and other information of the power grid to make the inverter AC power consistent with it. In addition, the grid-connected inverter also has functions such as maximum power point tracking (MPPT), islanding protection, power generation metering, and automatic adjustment and switching between online power sales and self-generation. It can be seen that the grid-connected inverter is no longer just an inverter, it has become a special device for photovoltaic grid-connected, but the name of the inverter is still retained. The power of the grid-connected inverter is usually above 5KW.

        Simply put, an inverter is an electronic device that converts low voltage (12 or 24 volts or 48 volts) direct current into 220 volts alternating current. Because we usually rectify 220 volt alternating current into direct current for use, and the inverter has the opposite effect, hence the name. We are in the "mobile" era, mobile office, mobile communication, mobile leisure and entertainment. In a mobile state, people not only need low-voltage DC power provided by batteries or batteries, but also need 220 volt AC power, which is essential in our daily environment. Frequency converters can meet our needs.
