Technical FAQs 4

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.

Why do power inverters lose power if switching frequency increases?

It is demonstrated that the power losses of power inverter are linearly increased with the rise of switching frequency, which is mainly caused by the switching losses of mosfet chips increment.

How does switching affect the efficiency of the inverter structure?

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.

How to analyze the losses of power inverter?

The losses of power inverter are analyzed separately for each circuit part, like DC-link, legs with power MOSFETs, or shunt resistor. The three-phase load is represented by R-L circuit, which is connected to star. This simulation model is going to help us to improve the efficiency of inverter and minimizing the greatest parts of losses. 2.
