Abstract :
This paper presents a new method to realize a digitally-controlled PWM inverter used in an online uninterruptible power supply (UPS). This digitally-controlled PWM inverter has been implemented using a digital signal processor (DSP). This implementation includes PWM pulse generation, voltage feedback loop (outer loop) and average current feedback loop (inner loop). Simulation and experimental results are given to verify the DSP based PWM inverter design and implementation
