The first direct calculation can be used, involving RMS and AV values of voltage and current. By this method, all types of power losses can be estimated . Second, the indirect calculation of the losses using instantaneous values of the voltage and current can be used. .
In this project, a three-phase inverter is used. Therefore, three voltage control signals the three different phases. are analyzed as mentioned in Section 2.2. For each of the following power modules, a specific datasheet is selected to show the step-by-step process for the power loss calculation.
The result from the power loss simulation of the three-phase inverter model can be seen in Fig. 4. The simulation is performed using FOC oriented to a rotor flux. At the beginning of the simulation, the motor starts at its nominal speed. If the target speed is reached, the load is attached in a time of 2 s to the motor shaft.
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.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
