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 pulse-width modulation in a high frequency inverter?

Pulse-width modulation to approximate the true sine wave by high frequency inverter. In the image above, the blue line shows the square wave varied by the length of the pulse and timing between pulses; the red curve shows how those alternating signals are modeled by a sine wave.

How can inverter frequency be adjusted?

External adjustment: Adjusting the input signal of the inverter, such as changing the frequency of the input signal, can adjust the output waveform frequency. Conclusion: In conclusion, understanding inverter frequency is essential for harnessing the full potential of AC power systems across a diverse range of applications.
