The difference between power frequency inverter and high frequency inverter

The power frequency inverter first inverts the DC into the power frequency low-voltage AC; Then through the power frequency transformer to 220V, 50Hz AC power for load use. Its advantage is that the structure is simple, and various protection functions can be realized at a lower voltage. Because there is a power frequency transformer between the inverter power supply and the load, the inverter power supply runs stably, reliably, has strong overload capacity and shock resistance, and can suppress the high-order harmonic components in the waveform. However, the power frequency transformer also has the problem of heavy and high price, and its efficiency is also relatively low.
