180-degree conduction with star connected resistive load:
The configuration of the three-phase inverter with star connected resistive load as shown in the figure. The following convention is followed.
- A current leaving a node point a, b or c and entering the neutral point n is assumed to be positive.
- All the three resistances are equal, Ra = Rb = Rc = R
In this mode of operation, each switch conducts for 180°. Hence at any instant of time three switches remain on. There are six possible modes of operation in a cycle and each mode is of 60° duration and the explanation of each mode is as follows:

Degree conduction, each phase conducts for 180 degrees, or half of the 360-degree electrical cycle. This means that each phase is active for a duration of 180 degrees, while the other two phases are inactive.
During the active phase, the input DC voltage is converted into an AC output voltage by switching the transistors or switches in the inverter circuit. The switches are turned on and off in a specific sequence to create a sinusoidal output waveform.
The inactive phases are not conducting and do not contribute to the output voltage. However, they play an important role in creating a balanced output waveform. The inactive phases provide a path for the current to flow back to the DC source, completing the circuit.
By controlling the switching sequence of the transistors, the inverter can generate a 3-phase AC output with a fixed amplitude and frequency. The 180-degree conduction allows for a balanced output waveform, which is important for the operation of 3-phase loads such as motors.
Overall, a 3-phase inverter with 180-degree conduction provides a controlled and balanced AC output voltage from a DC input source.
