Solar based DC-DC converter for armature voltage
controlled separately excited motor is implemented. Depends
on firing angle speed, torque and armature current of motor is
varied. This circuit output side PI filter is used. Because in the
PI filter output voltage side ripples level is less as compared to
capacitive filter so the experimentally get good output voltage
simultaneously for improving the efficiency also. The features
of the converter can operate with an excellent input power
factor. The operation of the converter is explained and
experimental results are also confirmed and its feasibility is
presented. As per experimental result that the proposed circuit
was derived by integrated buck-boost power factor correction
(PFC).Converter is given better result then the existing system.
