The output of three phase rectifier is fed to filter and after filtering the pure DC is fed to the load. To make the output voltage of the two converters in same polarity and magnitude, the firing angles of the thyristors have to be controlled. And also by using the thyristors device can be made to work in either it's inverting or motering mode or in both mode. The microcontroller is used as the firing controller.
