The paper describes the operation and elements of a three-phase bridge inverter in a way that simulates the operation of the inverter with ideal components in the software package Plecs and the simulation results were compared with the performance of a commercial solution. The simulation was performed using a three-phase induction machine in the unloaded and loaded state of a known load, and the parameters of the simulation induction machine were taken from a real 0.55 kW KZK90L8 motor manufactured by Sever. Due to the ease of access to the test points for the example of a commercial inverter, a test three-phase bridge inverter type EVAL-M1-IM828- A with a control module type EVALM1101TTOBO2 was applied. The aim of the study was to analyze and simulate the operation of a three-phase bridge inverter in the computer program Plecs and to compare the results with a commercial solution. It was found in the paper that computer simulations with ideal components, the operation of the final assembly can be well predicted.
