Technical FAQs 4

Are modern inverters good generators of sinusoidal voltage?

The aim of this «Cahier Technique» is to clarify this point and to demonstrate that modern inverters are excellent generators of sinusoidal voltage even when they supply non-linear loads. This is considered quite normal as UPS are designed and very often utilised to supply computer/ microprocessor systems which draw non-sinusoidal currents.

What is the output voltage waveform of an inverter?

The output voltage waveform of an inverter is non-sinusoidal. It contains a rich harmonic content. The Harmonic Reduction cause additional losses and torque pulsations if a three phase motor is used as a load. These torque pulsations pose a problem at low speeds.

Is alternating non-sinusoidal current normal?

This is considered quite normal as UPS are designed and very often utilised to supply computer/ microprocessor systems which draw non-sinusoidal currents. As alternating non-sinusoidal currents and voltages are the main topic of this study, it will be worth while to review the electric quantities in the presence of harmonics.

What is the harmonic distortion of a sine wave inverter?

If a sine wave is produced using pulse width modulation techniques, then high-frequency sine wave harmonics are introduced into the waveform and must be eliminated before supplying a pure sine wave voltage to the grid. High-quality grid-tied inverters have a total harmonic distortion (THD) of less than 5%.
