An inverter is a device that converts direct current (DC) to alternating current (AC) to meet the power demand of an AC load. According to the topology, inverters can be divided into high frequency inverters and power frequency inverters.

High-voltage direct current, and finally obtain 220V power frequency AC power for the load through the power frequency inverter circuit.

Since the high-frequency inverter adopts the high-frequency magnetic core material with small volume and light weight, the power density of the circuit is greatly improved, so that the no-load loss of the inverter power supply is small, and the inverter efficiency is improved. Usually, the high frequency inverter used in small and medium PVS, its peak conversion efficiency can reach more than 90%.

Its advantage is that the structure is simple, and various protection functions can be realized at lower voltages. Because there is a power frequency transformer between the inverter power supply and the load, the inverter runs stably, reliably, with strong overload capacity and shock resistance, and can suppress the high-order harmonic components in the waveform. However, power frequency transformers are also bulky and expensive, and their efficiency is relatively low. The rated load efficiency of the small power frequency inverter produced at the current level generally does not exceed 90%. At the same time, the iron loss of the power frequency transformer is basically unchanged when it operates under full load and light load, so it operates under light load. The no-load loss is larger and the efficiency is lower.
