Unlike single-phase inverters that produce one AC waveform, a 3 phase inverter circuit diagram shows six switching elements arranged to generate three sinusoidal voltages displaced by 120° from each other.

Now let us look into the 3 Phase Inverter Circuitand its ideal simplified form. Below is a three-phase inverter circuit diagram designed using thyristors & diode(for voltage spike protection) And below is a three-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.

The 120º mode is similar to 180º at all aspects except the closing time of each switch is reduced to 120, which were 180 before. As usual, let’s start switching sequence by closing the switch S1 in the first segment and be the start number to 0º. Since the selected time of conduction is 120º the switch S1 will be opened after 120º, so the S1.
