Overview

The IDDK offers an integrated-drive design with a full-power stage to drive a 3-phase motor, easing evaluation of a diverse range of feedback sensing and control topologies. The kit includes a 180-pin HSEC controlCARD based on the TMS320F28379D C2000 Delfino™ MCU, which integrates dual C28x real-time processing cores and dual CLA real-time coprocessors that provide 800 MIPS of floating-point performance with integrated trigonometric and FFT acceleration.

The sophisticated sensing peripherals on the TMS320F28379D MCU include sigma-delta filter modules with up to eight input channels, four high-performance 16-bit ADCs, and eight windowed comparators. These peripherals enable the IDDK to support shunt, flux gate/HALL, and sigma-delta current sensing simultaneously. For position feedback, the IDDK leverages integrated MCU support for the resolver and incremental encoder interfaces. In addition, customers can also explore configuration options that place the MCU on either side of the high-voltage isolation barrier.

TI designed the kit to plug into 110-V/220-V AC mains, deliver up to 8 amps, and to drive motors to 1 horsepower.

WARNING

TI intends this EVM to be operated in a lab environment only and does not consider it to be a finished product for general consumer use.

TI intends this EVM to be used only by qualified engineers and technicians familiar with risks associated with handling high-voltage electrical and mechanical components, systems, and subsystems.

This equipment operates at voltages and currents that can cause shock, fire, and/or injure you if not properly handled or applied. Use the equipment with necessary caution and appropriate safeguards to avoid injuring yourself or damaging property.

TI considers it the user’s responsibility to confirm that the voltages and isolation requirements are identified and understood before energizing the board and or simulation. When energized, do not touch the EVM or components connected to the EVM.
