Q. A single phase full bridge VSI has an inductor load. For constant source voltage, the current through the inverter is
Solution:
- For a VSI , the output current is square wave only for a purely resistive load.
- For RL , RLC loads the load current changes from square wave to triangular wave and exact shape depends on the type of damping in load.
- Thus from options Triangular wave is the most appropriate.
