PCIM: Inverter reference design targets e-mobility R&D

These designs further reduce time-to-market for R&D engineers in the rapidly evolving e-mobility arena.

Whereas 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 aluminium housing, this 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.
