A buck-boost converter provides an output voltage that can be either less than or greater than the dc input voltage VS. Hence the name “buck boost”. The output voltage polarity is opposite to that of the input voltage. It is a combination of buck and boost converters.
Figure 1: Voltage Source Converter. Symbolic representation of a voltage sourced convener is as shown in figure 1. The symbol has a box with a gate tum-off device paralleled by a reverse diode, and a D.C capacitor as its voltage source.

In the dc-dc buck converter, the input voltage is constant dc voltage whereas the output voltage is a variable dc voltage and the output voltage is lower than the input voltage. Hence the name dc-dc buck converter. Figure 1: Circuit Diagram of Buck Converter.

Permanent magnet motors are similar to conventional DC motors except the use of permanent magnet to produce flux instead of field winding. The use of high energy permanent magnet in the motors which advances in the field for the purpose of simplicity and low initial cost has led to the formation of new class of
