The power losses in a voltage source inverter (VSI) are the sum of the additional constant power losses of the local power supply, the inverter circuits as well as the main power conversion losses.
In high-power FCs, losses arising in the uncon trolled rectifier and autonomous voltage inverter may be critical , . The current investigation deals with studying power losses in the inver ter and rectifier cir cuits. Currently, these lo sses can be accurately calculated using var ious methods.
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.
The switching behavior of the power devices generates power losses switching frequencies will contribute to further increase the power losses . As a result, applications improve the efficiency of the inverter structure . Power losses are divided into two main categories: the conduction and switching losses.
