How to Build a Static 3-Phase Converter

Are you in search for a device that can help you lessen the electric consumption in your home? Do you want to conserve electricity in your office? Are you looking for an effective device that can be used to discharge and charge capacitators? Then learn how to build a static 3-phase converter. This device is very useful in starting electric circuits and saving energy. Below are the guidelines and basic steps in making a reliable and safe static 3-phase converter.

Tools and Materials

Before making this converter, it is best to gather all the necessary materials such as an idler motor, wires that have various lengths, run capacitators as well as start capacitators. Other needed materials in this project are plastic tapes, plugs, rubber gloves and a riley. Aside from these materials, get all the tools like a measuring tape, switches, nails, plugs and a voltmeter.


To start building a static 3-phase converter, it is necessary to know the different local wiring codes. Be sure that you only use the code that is reliable. To assure that the converter will function efficiently, remember to ground its frame. After doing this, the next step is to choose the most effective and functional 3-phase idler motor. Always check the motor’s nameplate before installing it to the main frame of the converter.

After installing the motor, select start capacitators and run capacitators based on the motor’s specifications. Refer to the blueprint before installing the capacitators to the frame. As soon as the capacitators are ready, proceed with the addition of fuses. To do this, be sure to make and refer to a schematic diagram so that the fuses will be placed in the right locations.

Check the flow of current before selecting the size of the wire that will be used. Afterwards, wire the overloads and the run capacitators. It is important that the voltage drop does not exceed three per cent. After wiring the capacitators, it is best to perform several current balancing tests. If the results of the tests are fine, then the next move is to evaluate if the converter is functioning based on the specifications. Finally, install a plug or a disconnect switch to ensure the safety of users.

Additional Tips

Always follow safety hazards as well as precautions when building a static 3-phase converter. Do not forget to wear rubber gloves when testing the conductors to avoid experiencing electric shocks. To finish this project successfully, prepare a blueprint of the design of the converter before making the device.
