The DC supply generally tapped
from the converter circuit . This is well known that
PMDC drives needs constant input supply to deliver
constant output for the load. Since majority of the supply
voltage is being wasted as switching losses in the
converter, the converter circuit does not provide constant
supply for the PMDC drives. Hence an idea of
minimizing the switching losses of the converter is taken
in to consideration. The Bridgeless Boost converter and
Double Boost converter are the right choices for analysis
for PMDC Drive to deliver constant output. Since the
switching losses of the converters decides the efficiency of the PMDC drive, the performance of the bridgeless
boost converter and Double boost converter are analyzed
through MATLAB simulation.
