Controllers for Phase Converters

A controller switches capacitors in and out to optimise the three-phase voltage.
Capacitors support starting load motors; motors accelerate fast.

Multiple run capacitors balance output voltages for sensitive loads such as CNC, VFD, inverter welders and plasma cutters.

Capacitors are selected at zero crossing moments in the sine wave.
Due to this soft selection method, capacitor life expectancy is high.
The output waveform is pure sine wave.

Converters with these controllers offer fast starts, high overload capacity and a perfect voltage symmetry.
There is no need to oversize a single to three-phase converter.
