Product overview
Description
The STDES-AKI003V1 provides an accurate current sensing for high-end industrial motor control applications based on three-phase inverter topology. It is a solution tailored for high-end servo drive.
It has been designed to be used in place of the STEVAL-CTM008V1 within the STEVAL-CTM009V1 kit. A complete system can be arranged using the STEVAL-CTM009V1, the STM32H7B3I-EVAL as control board and the STDES-AKI003V1.
The board features three ISOSD61 16-bit isolated sigma-delta modulators with low voltage differential signaling (LVDS) and single-ended options.
The solution features six power metal strip shunt resistors (two in parallel for each phase) of 5 mΩ 7 W for the current sensing placed inline with the motor phases.
The STDES-AKI003V1 allows the insulated current sensors (ICS) for phase currents reading via a dedicated 20-pin connector for sigma-delta streams compatible with the STM32H7B3I-EVAL board.
A customized version of X-CUBE-MCSDK firmware exploiting the sigma-delta hardware and filtering capabilities of the STM32H7B3I-EVAL is available.
The STDES-AKI003V1 three-phase sigma-delta current sensing board is a fully assembled board developed for performance evaluation only, not available for sale.
