Losses in two-level inverters have been reported extensively in the literature. Researchers have also investigated semiconductor losses in three-level inverters. Estimates of switching losses have been obtained using approximations of IGBT and diode I-V switching characteristics [1, 4, 17, 18].
The process of selecting the topology, components and operating parameters (voltage, current and switching frequency) of an inverter is highly affected by the anticipated inverter losses. An accurate estimate of the losses occurring in each part of an inverter can significantly contribute to achieving an enhanced inverter design.
Therefore, several commercial simulation tools have been established to accurately estimate the power losses of an inverter and improve its performance. The goal of this project is to design an application capable of estimat-ing the power losses of a three-phase, hard-switched inverter using various power semi-conductor devices.
