General Description
This Starter Kit offers optimal mechanical and electrical integration of OLEA® T222 FPCU-based controller board and OLEA® APP INVERTER application software from Silicon Mobility together with 3-Phase 1200V/550A1 SiC MOSFET Intelligent Mod-ule (IPM) from CISSOID.
This unique integration of a highly integrated and low losses SiC IPM with an ultra-fast, low power consumption, and critically safe real-time controller is setting new levels in terms of power density and efficiency for electric motor inverters.
Integrated hardware and application soft-ware support the rapid development of SiC inverters for compact and efficient motor drives in E-Mobility applications.
The platform is supplied with highly configu-rable control application software supporting various types of electric motors and position sensors.
