Why choose a modified sine wave inverter?

For running typical resistive loads like lights and appliances, 

a modified sine wave inverter is a reliable, cost-effective choice. 

Though modified sine wave inverters do not produce a perfect replica of AC true sine wave power,

 they do provide an affordable option that for many mobile power applications, is perfectly adequate.

 Some devices, however, may not recognize the modified sine wave and may run poorly or not at all. 

The solution to these issues is to purchase a Go Power! pure sine wave inverter. For most applications though, 

a Go Power modified sine wave inverter is a reliable and cost-effective mobile-power solution. See our Inverter Comparison  or Sizing Chart for details.



he terminology "modified sine wave" has come into use and refers to an output waveform that is a useful rough approximation of a sine wave for power translation purposes.

The waveform in commercially available modified-sine-wave inverters is a square wave with a pause before the polarity transition, which only needs to cycle through a three-position switch that outputs forward, off, and reverse output at the pre-determined frequency.

Switching states are developed for positive, negative and zero voltages as per the patterns given in the switching Table 2. The peak voltage to RMS voltage do not maintain the same relationship as for a sine wave. 

The DC bus voltage may be actively regulated or the "on" and "off" times can be modified to maintain the same RMS value output up to the DC bus voltage to compensate for DC bus voltage variation.

The ratio of on to off time can be adjusted to vary the RMS voltage while maintaining a constant frequency with a technique called PWM. 

The generated gate pulses are given to each switch in accordance with the developed pattern and thus the output is obtained. Harmonic spectrum in the output depends on the width of the pulses and the modulation frequency
