Advantages and Disadvantages of Parallel Inverter
Advantages :
- The load voltage waveform is not dependent on the load, as it does in series inverter.
- Only two SCRS are required as compared to at least four in bridge inverter configuration. (additional auxiliary SCRS are also required in bridge configuration).
- It uses the simple class C commutation.
- It is a simple and economical circuit.
- With the help of a filter connected on the output side, it is possible to obtain a good quality sinewave at the output.
- Commutation components do not have to carry the entire load current.
Disadvantages :
- The centre tapped output transformer is essential for the operation of the circuit. The transformer efficiency will not be 100% hence the efficiency of this type of inverter will be reduced.
- There is always a possibility of magnetic saturation of the core.
- This circuit is suitable to handle only fixed loads.
