Description

The Texas Instruments (TI)(tm) TMS320F240 digital signal processor (DSP) controller contains a hardware deadband unit that automatically generates a deadband in the six PWM (pulse width modulation) signals from the full compare unit. This document describes how the DSP can use the other six available PWM signals to drive a second three-phase inverter with deadband.
