Design Of Single Phase Inverter Using PID Controller For Nonlinear Load Application

The purpose of this paper presents a single-phase transformer-based inverter for nonlinear load application by using a PID controller.An implementation of an integrated Proportional,Integral,and Derivative(PID)controller for single-phase inverters is presented.Furthermore,the suggested controller for controlling output voltage is a PID controller.It functions as a voltage controller for inverter control,removing steady-state error in heavy-load applications.This inverter will be both efficient and inexpensive in terms of energy savings due to the improved waveform output and reduced steady-state error.Under nonlinear load conditions,a capacitive full-bridge circuit is used to provide instant current and thereby reduce harmonics.To remove the DC variable and steadystate error under heavy load applications,a new proportional plus integral controller for inverter control is proposed.In our proposed method,the DC component value and THD% is reduced to a very good level which is less than 5%.PID controllers that function as voltage controllers and DC offset cancellers are included in the proposed controllers.MATLAB Software was used to generate the experimental effect.
