ZEBHRA Converter for zero emission rollingstock
ZEBHRA is a custom-built converter designed specifically for zero-emission rollingstock, capable of powering vehicles with configurations of up to six axles. This integrated converter system features multiple inbuilt converters, including the Generator Power Converter (GPC), Traction Motor Power Converters (MPC), Traction Battery Buck-Boost Converter (TBBC), Auxiliary Power Inverter (API), 24 V DC Battery Charger (BC), Drive Control Electric Unit (DCU), and Dynamic Braking Voltage Limiting Unit (VLU). A key feature of ZEBHRA is its SIL 2 certified traction cut-off for Motor Power Converters, providing a robust safety mechanism.
The converter’s size, shape, and configuration are adaptable, allowing customization to accommodate various spatial and operational requirements. Within the ZEBHRA cabinet, IGBTs with integrated freewheeling diodes are used as active switching components, while the 24 V Battery Charger utilizes advanced Silicon Carbide (SiC) modules to optimize performance and efficiency. All power modules share a common liquid cooling system, and temperature sensors actively monitor each module to prevent overheating.
Each IGBT is managed by a dedicated Gate Drive (GD) card, which controls switching actions and offers protection against fault conditions, including short circuits. These GD cards interact continuously with the control computer for enhanced protection and operational integrity. Each converter within the ZEBHRA system is equipped with independent control electronics, ensuring precise control and comprehensive protection across all functions.
ZEBHRA Converters comply with rigorous international standards, including EN, IEC, ERA, ERTMS, UIC, and EU regulations, making them suitable for global applications.
