Three Phase Inverter Circuit Diagram - 120 Degree and 180
2019.11.29 Step3: (for 120 to 180) S1, S3S6 are closed while the remaining three switches are open. In such a case, the simplified circuit can be drawn as below. So for 120 to 180: Vao = Vbo= Vs/3 ; Vco = -2Vs/3. By using these we can derive the line voltages as: Vab = Vao – V bo = 0 Vbc = Vbo – Vco = Vs Vca = Vco – Vao = -Vs.
