Power supply systems for onboard applications

A large part of our portfolio constitute power static converters, which are used to supply railway vehicles, to charge vehicle batteries and for power supply of 1f and 3f appliances. By using digital control of the convertors, deploying the computer models in the development and use of new technologies, our products acquire remarkable parameters. For example:
