ISC41 - Single pack

The SciMo ISC41 Single Pack represents a state-of-the-art solution in power electronics, specifically designed for high-performance unmanned platforms, electric aviation, and heavy-duty e-mobility. The system integrates a high-efficiency power stage with an FPGA-based control unit in a single, IP65-rated housing, optimized for liquid cooling.

Advanced SiC Power Stage Utilizing a 6-pulse bridge topology with Silicon Carbide (SiC) MOSFETs, the ISC41 achieves significantly lower switching losses compared to traditional Silicon IGBTs. This allows for higher switching frequencies, which is critical for driving high-speed synchronous motors with low inductance. The inverter is capable of handling fundamental wave frequencies up to 2 kHz, ensuring smooth and precise control even at extreme RPMs.

Control Architecture At the core of the ISC41 is the Xilinx Zynq-7000 SoC, which combines a dual-core ARM processor with FPGA logic. This architecture allows for:

• Deterministic Control: Hard-real-time Field Oriented Control (FOC).

• Model-Based Algorithms: Superior management of motor saturation and flux-weakening regions.

• Parallel Processing: High-speed acquisition of sensor data (Sin/Cos, Resolver, ABZ) and safety monitoring without CPU overhead.

Thermal & Mechanical Integration Designed for harsh environments, the unit is fully sealed (IP65) and requires active liquid cooling. The cooling circuit is optimized for a 50:50 Water/Glycol mixture with a nominal flow rate of 10 l/min.

• Power Density: By delivering up to 390 kVA from a 5.2 kg unit, it offers one of the highest power-to-weight ratios in its class.

• Standardized Connectors: Power distribution is handled via Amphenol PowerLok series connectors, ensuring vibration resistance and high-voltage safety. LV signals and communications use a robust Souriau circular Mil-spec interface.
