<p>A converting device of electrical energy includes several single-phase bridge rectification circuits and several three-phase full-controlled bridge circuits. The first input terminals of the bridge rectification circuits are connected to output terminals of each phase of an AC power supplier relatively. The second input terminals of the bridge rectification circuits are connected each other. The two input terminals of each three-phase full-controlled bridge circuit are connected to the two output terminals of each bridge rectification circuit or connected to the two output terminals of each bridge rectification circuit via an inductance. When there is feedback of electrical energy from an electrical generation device to a power grid, the waveform coefficient of the current of the electrical generation device is improved, the harmonic wave is decreased, and the power factor is increased.</p> |
