IDVC^®, thanks to a suitable sizing of the power components and a remarkable response speed (<3milliseconds) is able to face lowering (SAG) of the grid voltage of a maximum duration of one minute. The energy required is taken directly from the network（Energy storage device）.

Current models are able to cover network downing up to 50% of the nominal value (-50%).

The voltage compensation on the buck/boost primary winding is performed by IGBT static switches controlled by a microcontroller. The microcontroller system monitors the output voltage and determines the opening or closing of the IGBT contacts ensuring the best regulation.

The use of the double conversion technology guarantees the insulation from the disturbances and the distortions of the network and, together with the help provided by the electrolytic capacitors, makes it possible to build machines for high power loads.

This SAG Compensator can operate with a load variation range for each phase from 0 to 100%, it is not affected by the power factor of the load and it can work with or without the neutral wire.

IDVC^® can operate with different input and, consequently, output voltage (380V or 415V) from the nominal one (400V).

The main components are:

• IGBT microcontroller-based electronic control boards running the system in terms of regulation and alarm management. They compare the output voltage value to the set one: if a difference is detected, they generate the compensation necessary to bring back the output voltage to the nominal value (provided that said difference falls in the working range).
• Conversion units (AC/DC rectififier and DC/AC inverter): Rectififier: it converts the phase to neutral voltage of the AC mains into DC voltage by means of a fullycontrolled IGBT bridge. The rectififier is sized in order to supply the inverter at full load. Inverter: it converts the DC voltage coming from the rectififier into AC voltage, stabilised in amplitude. The inverter uses the same IGBT technology as the rectififier.
• Internal by-pass static switch enabling load supply in case of fault condition.
• Buck/boost transformer adding or subtracting the voltage necessary to compensate for the mains flfluctuation.
• Touch display. The user interface is created using a multilingual «touch panel» (10"); through the selection menu, it is possible to display electrical values and set the operating parameters. It is also possible to communicate with the electronic component via the RS485 serial bus using the Modbus RTU protocol.
• The standard cabinet is metallic with RAL7035 color and IP21 protection degree.
