To produce a sine wave output, high-frequency inverters are used. These inverters use the pulse-width modification method: switching currents at high frequency, and for variable periods of time. For example, very narrow (short) pulses simulate a low voltage situation, and wide (long pulses) simulate high voltage.
Also, transformers are used here to vary the output voltage. Combination of pulses of different length and voltage results in a multi-stepped modified square wave, which closely matches the sine wave shape. The low frequency inverters typically operate at ~60 Hz frequency. To produce a sine wave output, high-frequency inverters are used.

The Sigineer low-frequency inverters can output a peak 300% surge power for 20 seconds, while high-frequency inverters can deliver 200% surge power for 5 seconds, check our HF solar power inverters. Low-frequency inverters take power impact through its big transformer which acts like a surge relief for the circuit.
The high frequency inverter can deliver the same power at higher frequency with a much smaller and lighter transformer, as a result, the HF inverter is often called transformer-less inverter, or TL inverter.
High frequency power inverters typically convert the DC to AC by driving the transistors at a much higher frequency from 50 Kilo Hz to a few million Hz. Low frequency inverter circuit diagram
