Technical FAQs 4
How do high frequency inverters produce a sine wave output?
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.
What type of inverter is used to produce a sine wave?
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.
What is the output current waveform of a pure sine wave inverter?
The output current waveform of a pure sine wave inverter is of high quality and can achieve low harmonic distortion when interfaced with a grid power supply.
What is a pure sine wave inverter?
Pure sine wave inverter: It produces a smooth, continuous waveform that closely resembles the AC power provided by the utility grid. The waveform is a true sine wave with a smooth and rounded shape. Modified sine wave inverter: It produces a waveform that is more like a stepped approximation of a sine wave.
