Build a Single to Three Phase Converter for 50Hz Supplies

SMP Ltd manufactures all of the components which incorporate all the functions needed to build a modern phase converter. There are three different types you can choose from: E, T, and F.


The type E converter is easier to build. It produces boost currents to support the starting load required whenever an external motor starts similar to other standard rotary converters on the market, it does not produce balanced voltages between phases. This is acceptable, for example, for basic machines in a home workshop environment that are not loaded to their limits and do not contain electronic circuits.

T and F controllers require more components and more assembly work but they do produce balanced voltages between phases as required, for example, by CNC machines, welders, plasma cutters, VSD drives and other electronic loads.

The type T controller is used for 4-12kW converters and has three high power switching devices.

The type F controller is used in converters 12kW and above. Both types enable motors and machines to produce their rated output.

Reading the wiring diagrams requires some electrical knowledge.

WARNING: Completed converters contain capacitors which remain charged even after the unit is turned off, always allow a few minutes for the capacitors to discharge through the discharge resistors before attempting any service procedures. NEVER OPERATE THE UNIT WITH THE COVER REMOVED!

All of the electrical testing and troubleshooting should be carried out by an experienced electrician.
