Worldwide climate changing and increasing of urbanization and demand for fastness and crossing connections inside and between the cities, comfort onboard, safety in infrastructure, costs saving and other technical/economical key factors are the most important topics in changing of paradigm for infrastructure keepers and more in general vehicles manufactures and operators.

RGM offers a wide range of power solution for infrastructure, signaling and rolling stock applications with a compact design and an high power density compared to available standard electronic devices.

Those targets have been achieved thanks to an advanced digital control with sophisticate algorithms designed to control the high modulation carrier frequency in soft switching mode. RGM’s converters are scalable in output power as well as for different voltage input and output in order to meet different applications.
