he ENERGY SAVING static converter serves to generate a controlled squarewave single-phase alternate voltage (low frequency: 25 ÷ 125Hz) for industrial applications requiring high load power supplied by an external matching transformer. The power supply, sectioned by remote control switch and external fuses, is fed by a three-phase electric line via uncontrolled diode bridge and filtered by inductor and capacitor battery. The DC voltage thus obtained is converted into single-phase alternating voltage via “H”-shape bridge of semiconductors in order to control impressed frequency single-phase transformers.
The IGBT (Insulated Gate Bipolar Transistor) technology provides an extremely efficiency control of high powers.
The benefits offered by this converters are:
