2 TRAMS TROLLEY-BUSES SUBWAY MEDCOM is a manufacturer of modern inverters for asynchronous drives and static converters installed in vehicles powered with 600 VDC/ 750 VDC voltage traction. Drive inverters are based on the IGBT technology. Owing to the application of modern control systems, they ensure anti-slip control of the drive torque of the respective vehicle axles, effective electrodynamics braking within the whole speed range of the vehicle and a possibility of emergency braking in case of blackout in the traction network. The currently produced inverters with output power range from 100 kw to 300 kw ensure very good driving parameters of the vehicle. Their main advantages are: low level of noise emission and ensuring a high driving comfort. The static converters with output power ranging from 5 kw to 100 kw ensure power supply for the subassemblies of the drive system and all other loads (control, lighting, compressors, fans of the devices) of the vehicle. Apart from that, the static converters may also supply the heating, ventilation and air conditioning systems. All the inverters and converters are equipped with a diagnostic-control system based on CAN 2.0B or RS232 interface 8

3 FT The FT drive traction inverter is designed for driving the 105N trams or similar ones. A direct microprocessorcontrolled (DSP) transistor converter (IGBT) has been applied in the system. The implemented control algorithm ensures optimal control of the motors speed (2 motors per an inverter) during the starting and electrodynamics braking (with or without recuperation). The inverter is equipped with a CAN 2.0B interface for control and diagnostics; it is also possible to set the torque with an analogue input. The control system checks periodically the motor insulation and temperature. The system is installed in the space previously occupied by the resistors (on roof mounting version is also available). The converter and braking resistors are cooled with forced (external) air from the fan of the traction motors.

5 FT The application of independent inverters for powering of single motors guarantees high traction parameters, perfect performance at the slip point and no influence of non-uniform wear of wheel s tyres on drive s performance. The FT drive inverter is a modern module inverter incorporating the IGBT technology. The converter control is in DSP technology (Digital Signal Processor) with application of Field Orientation Control Space Vector Pulse Width Modulation. The inverter system enables the drive to work with regulated torque, regenerative braking or rheostatic braking. The inverter has been equipped with an external air-cooling system, and can be built-up on the vehicle s roof (two inverter modules in one container). The inverter is controlled by the CAN 2.0 connection. The controller of the inverter has been equipped with an built-in antislip system. Additionally, the system is equipped with an emergency power supply system (from the vehicle s battery), it enables the vehicle to move out the intersectional isolator or crossing (in case of main power failure).
