Integrated Transformer with choke is a compact structural combination of a transformer which increases or reduces the voltage and a choke that functions as smoothing choke or a choke working in the filter system.

The purpose of this transformer is to provide a reliable galvanic isolation between load and power line. Subsequently, they also  provide protection against electric shocks or neutral connection that is isolated or grounded. The reinforced isolation and the electrostatic screen provides isolation even if the system is subject to severe atmospheric disturbance

Such a combination of the largest magnetic elements in one compact structure makes it possible to significantly reduce the volume and the total weight of the device as compared to the traditional solution. As less material used, lower transport costs, less magnetic elements for maintenance and shorter time of installation are the factors that affect the substantial reduction of a total maintenance cost of a choke transformer.
