STMicroelectronics STM32G473QB | Demoboard STEVAL-FTD01KCB

Beschreibung

The STEVAL-FTD01KCB evaluation kit is designed to provide a complete and modular fault-tolerant solution for a six-phase AC motor drive. The kit consists of the STEVAL-FTD01ACB Control Board, the STEVAL-FTD01BCB Main Board, and six STEVAL-FTD01CCB leg Power Boards.The Control Board has been designed as a 164 pins PCI Express® ready PCB, it hosts a STM32G473QB microcontroller (based on the Arm Cortex-M4 MCU, 170 MHz with 128 Kbytes of flash memory, math accelerator, high analog level integration), an STLINK V3 connector to program the MCU and make a serial communication with the PC.The Main Board represents the core part of the modular approach of this fault tolerant solution, in fact it is composed by six square holes where the Leg Boards could be mechanically fitted, it hosts a 164 pin female PCI Express® connector, six NTC sensing networks for inverter leg thermal protection, six fuses for short circuits protection, and six relays for phase opening, phase current and phase voltage sensing features. Moreover, the Main Board hosts two L6902D013 step-down switching regulators as an auxiliary power supply and the support for rotor position sensors (hall effect, incremental quadrature encoder and resolver).Each inverter Leg Board features the STGAP2D, a half-bridge gate driver to isolate the gate driving channels from the low voltage control and interface circuitry. The gate driver is characterized by 4 A capability and rail-to-rail outputs, making the device also suitable for high power inverter applications such as motor drivers in industrial applications. Moreover, the Leg Board hosts the trench gate field-stop, 650 V, 20 A, M series low-loss IGBT (STGB20M65DF2).The overall system is designed to be galvanically isolated between the MCU and power stages.
