They form the core of the switched mode power supplies used in real time applications. But the conventional DC -DC converter contains the voltage ripples due to the effect of the parasitic elements which is undesirable. The derived topologies of DC –DC converters from the conventional pumps eradicates this effect. In this paper the superlift LUO DC-DC converter will be presented which can replace the conventional converters. The effect of the parasitic elements is eradicated in superlift converter and range of the boosting the voltage level is high which will reduce the charging time and can be applicable for charging of o electric vehicles. The optimized proportional and integral controller using particle swarm optimization is applied to the presented converters.

INTRODUCTION Due to the advancement in the semiconductor technologies which form the core part of various vehicular applications ,aerospace, Photovoltaic systems etc ,DC-DC converters are gaining extreme importance. One of the main purpose DC –DC converters to create a high voltage DC link. The electronic pumps which have the DC –DC converter as it its core element are broadly categorized as fundamental pumps, derived pumps, transformer-type pump and super lift pumps. The fundamental pumps are generally buck,boost and buck-boost pumps and all other derived from the fundamental[1]. In basic topologies there is the effect of the parasitic elements but by using the advance pumps this effect can be minimized and voltage levels can be changed to more significant level. the Super lift pumps are further classified as Positive super Luo-pump, Negative super Luo-pump, Positive push-pull pump, Negative push-pull pump, Double/Enhanced circuit (DEC) eradicates the effect of the parasitic elements to a great extent[2]. Each of this topology is also further divided into various subcategories. The Positive Output Luo converter which is basically a boost converter and have a capability to enhance the voltage by the considerable amount is presented here. The conventional boosts converter contains the ripple in the output voltage due to the effect of the inherent Revised Manuscript Received on November 05, 2019.

But this paper presents the topology of the boost converter in which the effect of the parasitic elements is being reduced sufficiently and high levels of the voltage are obtained .Thus Luo converter are very beneficial for providing the DC link required in the Electric vehicle as it will reduce the charging time. II. POSITIVE OUTPUT SUPER LIFT LUO CONVERTERS Based on the number of switching devices and the enhancement in the voltage level[4] The positive out Luo converters are further classified as Main series: It consist of one main switching device ,n number of inductor , 2n number of capacitor and (2n-1)diodes, where n =1,2 ,3….for elementary circuit, relift ,triple lift so on. Additional Series: In this series there is one switching device, for nth stage n number of inductor,2(n+1) capacitor (3n+1) diodes Enhanced Series-In This type of series there is one switch, the nth stage there will be n inductors,4 capacitor and (5n-1) diodes. Re –Enhanced Series: In this circuit topology there is one switch ,for nth stage number of inductors are n, there are 6 capacitors and (7n—1)diodes. Multiple (j) Enhanced series- this topology has one switch and for nth stage of the converter there will be n inductors,2(1+j)n capacitors and [(3+2j)n—1] diodes. Additional Series :This series topologies have one switch, the number of inductors for the nth stage is n,2(n+1) capacitors are required and (3n+1) diodes will be used. In this paper Elementary topology , Re lift converter and triple lift topologies of Enhanced series Luo converter in the closed loop using different closed loop control techniques is being discussed.
