Abstract

In this paper, a switched mode PWM inverter control using a fixed-point digital signal processor (DSP) for an uninterruptable power supply is presented. Issues related with a real-time digital control design of an inverter system and a pulse width modulation (PWM) with a fixed point DSP are discussed, and it is shown that the programmability of a DSP facilitates implementing the overcurrent limit control with a droop method. The simulation and experimental results are presented to verify
