Inverter Control Board

All inverters produced by EMPEQ are based on the same architecture and use the same control hardware. This is built around a microcontroller from the Texas Instrument TMS320 series. In addition to the microcontroller, the control board contains all hardware for:

• interfacing to one three-phase or three single-phase intelligent power modules including current measurement;
• measurement of three AC phase voltages;
• measurement of two DC currents including overcurrent protection;
• four binary inputs;
• five relay outputs, one of which directly controlled by all hardware protections;
• serial interface for programming and supervisory control.

All interfaces are galvanically isolated from the microcontroller circuitry.
