(2004). Analytical Solution to Harmonic Characteristics of Three-Phase PWM Inverter Using 3-D Modulation Model. Electric Power Components and Systems: Vol. 32, No. 11, pp. 1105-1120. Shimano ultegra 6800 hubs
A basic three-phase inverter consists of three single-phase inverter switches each connected to one of the three load terminals. For the most basic control scheme, the operation of the three switches is coordinated so that one switch operates at each 60 degree point of the fundamental output waveform.

For example, a 5 kW single phase solar inverter working at maximum capacity would be feeding 5kW of solar power into one phase but a three phase 5kW solar inverter in the same situation would feed the power evenly into the 3 phases. 5 kW divided by 3 phases = 1.7 kW; that’s 1.7 kW of power feeding into each phase.

Three phase frequency converters accept three separate AC input phases and convert them to a single DC output. Most three phase frequency converters can also accept single phase (230V or 460V) power but, since there are only two incoming legs, the frequency converters output (HP) must be derated because the DC current produced is reduced proportionally.

This technique is called pulse width modulation. The operation of the pulse width modulation inverter, often shortened to PWM, can be explained with use of following Figure. In this example a triangle wave with frequency f d is compared with a symmetric three phase sine wave system. The intersections of the triangular wave, also called carrier ...
