dc.description.abstract	This research examines the performance of a single-phase PWM inverter equipped with a P, PD, PI and PID controllers. The research aims to decrease Total Harmonic Distortion (THD) in case of fixed and variable output voltages. To reduce THD, different controllers are used, which are tuned using PID tuner and Trial and Error methods , and the THD is measured using the Simulink powergui's FFT analysis tool. MATLAB Simulink is used for inverter modelling and simulation. For PI controller-based Inverter, the THD is 0.45% for fixed 400V output voltage and it is increased to 50.85% for rapidly changed output voltage. Furthermore, for PID controller-based Inverter, the THD is 0.01% for fixed 400V output voltage and it is increased to 52.41% for rapidly changed output voltage. So, PI controller-based inverter works better for rapidly changing output voltage, but the PID controller-based inverter performs better for fixed output voltage, according to the comparison analysis. This research also examines the performance analysis of Unipolar and Bipolar PWM techniques and finds which PWM technique gives least value of THD for PI and PID controller based inverters for both fixed and variable voltages. For PI controller-based inverter with unipolar PWM technique , the THD is 0.44% for fixed 400V output voltage and it is increased to 15.57% for rapidly changed output voltage. And for PI controller-based inverter with bipolar PWM technique , the THD is 3.58% for fixed 400V output voltage and it is increased to 16.41% for rapidly changed output voltage. Furthermore, for PID controller-based inverter with unipolar PWM technique , the THD is 0.01% for fixed 400V output voltage and it is increased to 15.98% for rapidly changed output voltage. And for PID controller-based inverter with bipolar PWM technique , the THD is 0.02% for fixed 400V output voltage and it is increased to 16.01% for rapidly changed output voltage. So, unipolar PWM technique performs better than bipolar PWM technique for both fixed and variable voltages	en_US
