Comparison of Single-Phase Inverter Using Proportional Resonant and Proportional Integral

The purpose of the study was to design a new single-phase inverter that is stable even if the source changes or the load changes using Proportional Resonant or Proportional Integral. This dissertation project studies the design of a 500W Power Single-Phase In-verter with 1K load. The input voltage of each controller, stabilizing the output and ensur-ing the THD value <5%. The study project simulated using MATLSB / SIMULINK ex-periments on the output voltage, THD from the set parameter value and, THD by adjusting the input voltage value as well as the control capacity of each controller on the load. And compare the capabilities of each controller.
