After
the other stages were designed successfully and tested well, it was not difficult
to design and test the AC load part. The final designed circuit is shown below:
The RLC AC load value is given: the active
power P is: 500 W; the inductive reactive Power QL is 200VAr; the capacitive
reactive power QC is: 500VAr.
It was simulated successfully. The curve of the line to line voltage at the output of the inverter and
the voltage at ac load is shown below:
Another scope was also added to display the
three phase line to line voltage:
The
output at dc load part is also display in the following figure:
