Regulation of speed of DC machine using super lift converter

In recent trends Direct Current (DC) machine is used in many areas of electrical machine drive systems because of its simplicity in construction, torque power and efficient speed control. The DC motor gives better and reliable performance along with higher torque. The speed control of DC motor is obtained by the use of Proportional Integral (PI) controller. PI controllers are largely used in the industries due to their structure simplicity and easiness in implementing them. Our aim is to be design of positive output super lift converter fed DC motor and to regulate the DC motor speed by using conventional controller. In a positive output super-lift converter the output voltage keeps on increasing progressively in each stage by a geometric progression and the voltage transfer gain is efficiently increased.
