The ENERGY SAVER static inverter is used to generate a controlled square-wave single-phase alternating voltage (low frequency: 25 ÷125Hz) in industrial applications requiring high load power supplied by an external matching transformer.
The remote control switch and the external fuses section the power supply powered by a three-phase electric line via uncontrolled diode bridge, and filtered by an inductor and a 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 efficient control of high powers.
The benefits offered by these converters are:
Reliability and efficiency typical of semiconductor devices
High efficiency (about 95%) and the possibility to control high power loads
Power factor cos(φ) = 0.9, no power factor correction is needed
Power taken from the line on each phase in a balanced way
Easy-to-use water cooling system
Usually, an external PLC control and manage the machine cycles
Energy saving up to 47,6% in SRC three-phase machines
