Abstract :
The fuzzy-tuning proportional-integral-derivative (PID) control of an inverter with rectifier-type nonlinear loads is described in this paper. The inverter system employs closed-loop instantaneous voltage feedback PID control with a sinusoidal reference implemented using a TI TMS320F240 digital signal processor (DSP). The output voltage error and its derivative are used as input variables of the fuzzy logic controller (FLC) to adjust the feedback gain of the system. Simulation and experiment results prove that the proposed converter is able to produce a low total harmonic distortion (THD) in the inverter output and fast dynamic response for rectifier-type nonlinear loads
