Technical FAQs 4

What are power losses in a voltage source inverter (VSI)?

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.

Are power losses arising in a high-power inverter critical?

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.

What is a serial equivalent resistance in a voltage source inverter?

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.

Does switching frequency increase power losses?

It is interesting that the power losses increased more with the switching frequency in the range 12,800–25,600 Hz than in the range 25,600–51,200 Hz ( Fig. 10 a and b).
