POWER: PCIM REVIEW

The integrated device also includes SPI (serial peripheral interface), SiC monitoring and protection and diagnostics for functional safety. The SPI programmability and integrated monitoring and protection features can reduce design complexity as well as external component costs, said TI. The company has also introduced an SiC EV traction inverter reference design which includes the UCC5880-Q1, Wolfspeed SiC devices, a bias-supply power module, real-time control microcontrollers and high-precision sensing. Design tools Simulation tools took a step forward when onsemi introduced the online Elite Power Simulator and Self-Service PLECS Model Generator software tools. (PLECS is the software tool for system level simulations of electrical circuits, developed by Plexim but adopted across the power industry.) onsemi announced the tools for its EliteSiC family in order to save designers time in selecting a product by being able to access simulation data. The models are generated based on typical or worst-case conditions and the designer can define application-spe- cific parasitics such as layout, the number of components and inductance information, for example, to generate PLECS models for specific system-level simulations. The tools can be used for designing ASICs, MOSFETs, discrete or module SiCs and are available free of charge and for limitless use. An SiC inverter reference design was showcased by Cissoid. It was jointly

developed with Silicon Mobility as a complete and modular reference design to reduce development time for electric motor drives up to 350kW/850V. At 400 x 400mm, the model was an update from the earlier, bulkier model. It uses Cissoid’s high voltage SiC-based power module, integrated gate driver board and control board with Silicon Mobility’s OLEA T222 field programmable control unit (FPCU), DC and phase current sensors, DC link capacitor and EMI filtering together with integrated liquid cooling. The reference design includes cables and sensors and is customisable with DC fixtures, said Cissoid’s CEO, Dave Hutton. Customers can buy the three-phase SiC inverter reference design from Cissoid with a license to use the Silicon Mobility’s OLEA App Inverter control software and design on top the software application,. Cissoid will provide technical support to integrate the inverter into the final motor drive system before production. The digital PCIM Europe 2023 event will be available online until 30 June 2023 at pcim-europe.com. PCIM Europe 2024 will be held at the Nuremberg Exhibition Centre from 11 to 13 June 2024.
