Q.Draw the circuit diagram and output waveforms of Inverter.

A single-phase inverter uses four IGBTs in a full bridge across a DC source, with the load between the two mid-points, and produces an ac square wave by switching diagonal pairs alternately. …

[!TLDR]

Four IGBTs form a bridge across $E_{dc}$; alternately gating the diagonal pairs makes a square ac wave of $\pm E_{dc}$ across the load.

Circuit: A single-phase full-bridge inverter uses four IGBTs $Q_1$, $Q_2$, $Q_3$ and $Q_4$ connected across a DC source $E_{dc}$ (top node X, bottom node Y). $Q_1$ and $Q_2$ form the left leg with mid-point A, and $Q_3$ and $Q_4$ form the right leg with mid-point B; the load is connected between the mid-points A and B. …
