Technical FAQs 4

How does a voltage source inverter work?

In the voltage source inverter (vsi), the switches are turned on and off at regular intervals to deliver rectangular pulses of voltage to each phase. Figure 1 shows the line-to-line voltages of the inverter, VAB, VBC, and VCA.

How to model a Voltage Source Inverter (VSI)?

To model a VSI, the first approach is based on theoretical calculations of the output voltage vOUT, coil current iLF, and output current iOUT during the single-switching cycle Tc for both switched on (VFIN = VDC) and switched off (VFIN = 0) time periods. The basic block diagram for this modelling approach is presented in Fig. 2.

What are the components of a voltage source inverter?

A typical voltage source inverter consists of power semiconductor devices (such as insulated gate bipolar transistors or IGBTs), gate driver circuits, control circuits, and filtering elements. What is the difference between a voltage source inverter and a current source inverter?

How can a single-phase voltage-source inverter be used to design a generic control system?

pplied to design a generic control system.
