Plans and tips to build digital single to three-phase converters 4kW to 24kW (5 to 30 hp)

Phase converters are used in metal or woodworking workshops, in meat processing, in bakeries, on dairy farms.
They run one or many three-phase machines on single phase power

Most rotary converters have the same known drawbacks:

- The generated phase output voltage varies too much with changing loads.
- Some CNC / PLC equipment, plasma cutters, VSDs will not work properly.
- Some manufacturers oversize their converters to improve the output voltage symmetry somewhat.
- One manufacturer offers add-on voltage stabilizers to make converters CNC / PLC compatible.
- Motors and machines cannot develop their full nameplate power with unbalanced voltages.
- Motors start and accelerate sluggishly. Read all this in various papers published by the phase converter industry

Change this, build a single to three-phase converter with the advanced features of a digital controller:

* Phase voltages are balanced to within 3%. Motors will develop their full nameplate power.
* Voltages remain symmetrical at all loads. CNC, PLC, VFDs, welders work well.
* No contactors, no electrolytic capacitors used. Such a converter will last.
* Solid-state capacitor switching at zero crossings. Perfect sine waves, no EMC emission, no harmonics.
* Power quality and emissions meet all industry standards.
* Motors and machines accelerate and reverse fast.
* No restrictions: All loads are allowed (motors, electronics, resistive, inductive, capacitive)
* Same specifications as Booster converters in the US and Australia and as the Digi-Phase in the UK

Assemble the parts inside a safe ventilated box.
Your electrician will finish the wiring if you are not an electrical expert

Details:
Install one or more standard three-phase motor on soft mounts outside or inside a box.
Install standard metalized polypropylene capacitors.
Install the digital single to three-phase Booster controller

Parts, controllers, complete kits, support and even complete solutions are available by several sources in the US, UK, Australia.
Sources and parts and other details are all published (google them) and also listed in the supplied documents

Installing the components is easy.
Reading the wiring diagrams requires electrical knowledge

You will receive:
Wiring diagrams for nine different converters 4kW to 24kW (5 to 30HP) based on controller types E and T and F.
Part specifications, building instructions, tips. Email and phone support.
16 pages. No movies, no books, not the internal circuitry of the digital controllers

You will still need:
A digital controller. A standard motor (delta wound is best).
Standard capacitors. Appliances wire. Connectors. A safe enclosure
An autotransformer if this is to be made for 50Hz.
The support of an electrician if you are not an electrical expert yourself.
Money back guarantee if you are not satisfied with plans or instructions or with the performance of your new converter

Supply voltage of your new Booster converter will be single phase 240V (208-240V)

Three-phase output will be:
in US and Canada: 3x 240V 60Hz.
in UK, Ireland, Europe, Asia, Australia: 3x 415V 50Hz
