Abstract: A 1 kVA inverter sample was designed with the digital signal processor TMS320LF2406 produced by TI company. The double closedloop control structure of output voltage instantaneous value and RMS value was adopted. The hardware and software of the inverter were presented in detail, and experiment was carried on. The dynamic and steady performances of the system are proved to be better by the experimental results.
Key words: inverter; sinusoidal pulsewidth modulation (SPWM); digital signal processor (DSP); double closedloop
