For the Control hardware the device MITRAC DCU (in the special version MITRAC CC DCU2) is used, which provides a unified converter control system for all types of converter control in Bombardier.The DCU is mounted upon the converter modules, so that all sensors and fiber optic channels are connected directly and on short way to DCU.All project specific adaptations are done only in application specific parts of the software, programmed with MT while the control hardware doesn’t need any configuration for application adaptation. All memory- and FPGA devices are in circuit programmable. The DCU must be supplied with the voltages +24 V and -24V, which are provided by a power supply device. This power supply device supplies one DCU and the GDU’s of the associated converter module and realizes a galvanic isolation from the battery voltage.
