This reference design implements a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors. This design uses the AMC1306E25 delta-sigma modulator for accurate shunt-based inline motor phase current sensing. The modulator output is Manchester encoded, simplifying clock and data signal routing between the MCU and the modulator. The modulator's high CMTI helps suppress inverter switching noise transients from causing data corruption on the controller side. A compact solution is achieved using a small size modulator. TIDA-00914 provides an interface to an external MCU or FPGA so that a SINC digital filter can be used to demodulate the AMC1306E25 output bit stream. This reference design uses the F28379D Delfino control card, which is connected to the card described in the reference design via an adapter card for current sensing using SINC filters.

A system basis chip (SBC) is an integrated circuit (IC) that combines several typical building blocks of a system, including transceivers, linear regulators, and switching regulators. While these integrated devices can provide size and cost savings in many applications, integrated devices do not work well in every situation. For applications that are less suitable for using an SBC, a better approach is to build discrete implementations of the above building blocks to create a discrete SBC.
