A 3 Phase Inverter converts the DC voltage into 3 Phase AC supply. Here in this tutorial, we will learn about Three Phase Inverter and its working, but before going any further let us have a look at the voltage waveforms of the three-phase line. In the above circuit, a three-phase line is connected to a resistive load and the load draws power from the line. If we draw the voltage waveforms for each phase then we will have a graph as shown in the figure. In the graph, we can see three voltage waveforms are out of phase with each other by 120º.
3 Phase Inverter Circuit which is used as DC to 3 phase AC converter. Do remember that, even in the modern days achieving a completely sinusoidal waveform for varying loads is extremely difficult and is not practical. So here we will discuss the working of an ideal three-phase converter circuit neglecting all the issues related to practical 3 phase inverter.
The ideal circuit is drawn before it can be divided into three segments namely segment one, segment two & segment three and we will use these notational in the later section of the article. Segment one consists of a pair of switches S1&S2, segment two consists of switching pair S3 &S4 and segment three consists of switching pair S5&S6. At any given time both the switches in the same segment should never be closed as it leads to battery short circuits failing the entire setup, so this scenario should be avoided at all times.
Now let’s start switching sequence by closing the switch S1 in the first segment of the ideal circuit and let’s name the start as 0º. Since the selected time of conduction is 180º the switch S1 will be closed from 0º to 180º.

[@ParthPatel-ie1ry]

can i get lab manual of power electronics subject using PSIM simulator ? or simulation files?

[@ElectroTechCC]

Hello Parth,
I don't have any manual for PSIM simulator, but you can find more details from internet about PSIM simulator.

[@black-sci]

Are you getting equal rms values for all three phases?

[@prathmeshakolkar4813]

Sir, use of PSIM is in syllabus or it is for extra knowledge?

[@ElectroTechCC]

You can consider in the syllabus, because without use of any simulation tool you can't complete your power electronics project

[@anggarawicaksono]

Hallo, i have a question

[@Mrpaul1975]

Ye sab computer mein acha lagta hai original mein banao dekho kitna difficulty aate hai

[@ElectroTechCC]

Ha, sahi hai ..

[@fendyulio]

can you send this file for me?
