It is known that in most of the cases, the country area just has a single-phase system to supply the electric energy. It is intended in this work, to purpose a simple, efficient and low cost static system conversion phases. The proposed system consists basically of a semicontrolled rectifier and a transistorized inverter that make the conversion DC- AC (direct current - alternating current). The system can be used in this way to supply three-phase induction in substitution of single phase ones, which is desirable. Also the operation in variable speed is achieved, therefore the converter of phases aim the constant motor flux operation, with the maintaining of the relationship voltage-frequency, for the motor startup and variable speed operation.
