CISSOID Ingenuity Facilitates Faster Inverter Development

­CISSOID, a leader in power semiconductor solutions, is introducing the compact EVK-PLA1060 series of On-Board Inverter Reference Designs. This exciting advance further reduces time-to-market for R&D engineers in the highly dynamic and rapidly evolving e-mobility arena. The increasingly wide range of Silicon Carbide (SiC) inverter reference designs, including this new On-Board Inverter Reference Design, is CISSOID’s product focus at the PCIM Europe 2024 exhibition (Hall 9, stand 622).

In a fast-paced industry like e-mobility, speed-to-market can often prove the difference between commercial success and failure. CISSOID therefore set about devising a way to accelerate the development process even more for traction inverters.

Whereas the existing Bench-Top Inverter Reference Designs are suitable for laboratory and bench-based motor testing, the On-Board Inverter Reference Design is far closer to production-ready. The result is a complete solution, conceived for integration into vehicles about to undergo in-vehicle and field testing, drastically reducing the time required for system development.

Featuring a compact and lightweight, yet robust aluminum housing, the EVK-PLA1060 On-Board Inverter Reference Design offers easy vehicle mounting with minimal design effort. Furthermore, the motor control software allows customization and configuration by the user for additional process simplification.

Driving the product’s functionality is Silicon Mobility’s ultra-fast OLEA® T222 FPCU (Field Programmable Control Unit). Dedicated to e-motor control, the programmable hardware of this application-specific processor accelerates response times to critical events, off-loads the processor cores and enhances functional safety.

The programmable hardware of the T222 processor enables fast control loops and high switching frequencies, combined with the OLEA® APP - T222 INVERTER control software, offering powerful optimizations such as dead-time compensation and advanced modulations, this high-performance, real-time solution is fully configurable for use with various e-motor types.

Both the OLEA® T222 processor and OLEA® APP - T222 INVERTER software carry ISO26262 ASIL-D and AUTOSAR 4.3 certification, while the ISO26262 certification of CISSOID’s ICMs (Inverter Control Modules) is currently in progress.

As a highly modular solution, the EVK-PLA1060 On-Board Inverter Reference Design is configurable and customizable as required. It consists of a power module, the control board, a low ESL (equivalent series inductance)  DC-link capacitor, a compact EMC (electro-magnetic compatibility) filter and current sensors.

The EVK-PLA1060 On-Board Inverter Reference Design provides a broad power range of 100 to 350kW, at a 100 to 850V operating bus voltage, offering the potential for a power density up to 52kW per litre.

This innovative On-Board Inverter Reference Design ultimately offers a complete and uniquely modular solution for those seeking further reductions in time-to-market for electric motor drivetrains. With its potential for integration at vehicle field testing stage, R&D engineers can use this important industry advance to step into the future of high efficiency inverter design and development.
