Abstract :

 A DC–DC converter topology the controllable switches are operated switch mode where they turn entire load current ON–OFF during each switching cycle. Under these conditions the switches are subjected to high switching stress and power losses. Reasonly there is an increased interested in use of switched capacitor type DCDC converter. Due to the advantage of high frequency of operation, high efficiency, small size, lightweight, Reduced electromagnetic interference (EMI) and low component stress. DC–DC multiple–lift PUSH–PULL switched capacitor luo converter. Find the application especially in telecommunication power supply, battery charging, aircrafts converter systems and fuel cell power system. The above converter are also employed in a personal computer ,laptop computer and plasma power supplies. A voltage lift techniques is a popular method to apply in electronic circuit design. The present work is on the performance evaluation of negative output multiple lift PUSH PULL SC luo converter. MATLAB software are used to study the dynamics characteristics and analysis the closed loop performance of these converter with Resistive load, supply and load disturbance. The simulation closed match with each other and high light the feasibility and validity of the developed control scheme.
