Mar 3, 2023 · So I''m gonna explain to you guys in simple words about what you can run on your any size inverter and what are the key point to keep in mind.
Free QuoteThe 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.
The inverter power sizing is a delicate and debated problem. PVsyst provides a graphical tool (button Show sizing) for the study and understanding of the sub-array sizing, concerning either the array voltage (number of modules in series), and the array power (number of strings). In this tool, the upper graph concerns the Array voltage sizing.
The Phase-A leg is implemented using three Half-bridge IGBT with Loss Calculation blocks. Both switching and conduction losses are calculated and injected into a thermal network. The simulation illustrates the achievable output power versus switching frequency for the three-phase, 3-level inverter.
Run the simulation and observe the following operating points: From t=0 sec to t=5 sec: the inverter outputs 372 kW (power factor = 0.85) using a switching frequency of 850 Hz. The converter total losses are 2.7 kW and the highest junction temperature (125 C) is observed on IGBT1 of Module 1 (or IGBT2 of Module 2).
From a +/- 1800 volts DC source, a 400-kW, three-phase 3-level inverter delivers variable power to a distribution power system. The inverter output is connected to the 25-kV, 40 MVA, 50-Hz system through a 2200 V / 25 kV transformer. The inverter topology is based on the model described in .
Results The concept of using one serial equivalent resistance (that is dependent on the switching frequency and the load current and that presents all of the static and dynamic power losses of the power conversion) enables the easy calculation of the losses and the efficiency of the voltage source inverter.
