AC-AC Converters
START POWER S.r.l. (Start Power)
AC/AC converters, also known as frequency converters or voltage converters, are electronic devices used to convert electrical energy from one type of alternating current (AC) to another alternating current with a different frequency or voltage. Start Power offers single-phase stabilisers, three-phase stabilisers and energy saver static converters.

Energy Saving Static Converter
-
The 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.

Three-Phase Converters
SIRIO 3PH 7 ALFA 3PHSAP
-
The three-phase converter is an electronic equipment able to vary the RMS value of a sinusoidal voltage by controlling no. 6 controlled, antiparallel-connected conducting diode pairs.Since the wave form is symmetrically split both into positive and negative halfwave, the output voltage average value is not affected and equal to zero. This means that three-phase loads can be fed without gene rating inside the mesh a circulating current with average value other than zero.Moreover, the three-phase converting is obtained with only one control circuit thus ensuring balance between the three linked voltages applied to the load.

Single Phase Converter
Series Sirio AC / ACS
-
The SIRIO single-phase equaliser is an electronic device that offers the ability to regulate the rms value of a sinusoidal voltage through the control of two diodes connected in antiparallel.
