The authors have proposed that ΔΣ modulator is effectively applied to an inverter system with PWM pattern generating scheme. The major features of ΔΣAE modulator is the inherent nature of spread spectrum and simple configuration. On the other hand, ΔΣ modulator can be considered as a sort of error amplifier. Using proposed ΔΣ modulator, an automatic amplitude control function will be realized. In this paper, an automatic amplitude control performance of ΔΣ modulated voltage source inverter is described. The results of computer simulation and FFT analysis indicate that output influence due to DC source variation are effectively reduced by ΔΣ modulator. Furthermore, a possibility of system design simplification is described in this paper.
