Your Experts for
power converter

Do you need customized power converter solutions for your large-scale application?

Current and rectifier from SIK Industries
Power converters are able to change the type of current or parameters such as frequency and voltage. Thus, a conversion from three-phase to direct current is applied from power generation to power transmission. SIK Industries plays an important role in this infrastructural supply function by developing highly reliable rectifiers.

Reliable inverters
After transmission, the currents must be provided again as alternating current decentrally to the 240V supply. For this purpose, we also supply you with the required inverters of the highest quality.

Let us realize your project together!
We are your contact for individual components, machines and devices for all industrial applications, which are to be developed both new and existing.

Solutions for different
Fields of application

Traction Inverter

Modern drive systems in rail transport are characterized by reliable, powerful three-phase motors. To supply these drives with power, the corresponding three-phase power supply system is required on board.

SIK Industries supplies the traction converters on IGBT basis. Here, IGBT semiconductor technology offers you the greatest flexibility in application. With the help of this technology you can operate the supply of your drive systems with the most modern technology.

Auxiliary converters

Auxiliary converters are used to create the connection between consumers and the energy supply of vehicles. They are a key element in passenger comfort and enable the operation of air conditioning systems and 240V sockets for charging passengers' personal electronic devices.

With auxiliary converters from SIK Industries it is possible to easily and reliably set up a three-phase on-board power supply system in your vehicle to supply three-phase auxiliary units.
