Explain operation of series inverter with neat circuit diagram and waveform.

Ans:

Working:

• When S1 (T1) is triggered the capacitor starts charging with left side plate positive with respect to right and when the voltage on capacitor is slightly greater than Edc T1 turns off; but there is no discharge path for capacitor hence it holds the charge.  

•  When trigger pulse is applied to T2, T2 start conducting and current starts flowing in opposite direction.  

•  In this way due to charge and discharge of capacitor and switching of T1 and T2 current will flow in RC.  

•  Hence sinusoidal current starts flowing in the load.
