High-frequency inverters generate the AC output waveform by switching power devices at frequencies much higher than the output frequency. Some key characteristics: They contrast with line-frequency inverters operating nearer to the AC output frequency. [Diagram] The inverter bridge contains power switches like IGBTs or MOSFETs.
The output frequency depends on how fast the switches cycle on and off. Common high-frequency inverter circuit configurations include: Key design factors for high-frequency inverters: Switching frequency – Higher frequency allows smaller filter components but increases losses. Optimize based on tradeoffs.
The low frequency inverters typically operate at ~60 Hz frequency. 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.

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.
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
