DC microgrids are well known due to the combination of sustainable power sources, for example, sun based photovoltaic and power device. Inferable from the low yield voltage of these DC power generators, high proficient high addition DC-DC converters are deprived to associate the DC microgrid. In this paper, a non-confined high addition dc–dc converter is proposed without utilizing voltage multiplier cell (VMC). The proposed topology uses two non-confined inductors that are associated in series/parallel during liberating/charging mode. The activity of switches with two distinctive duty ratio is the principle key factor of the converter to accomplish high voltage gain without using outrageous duty ratio. Likewise, a 100W, 20/200V model circuit of the high voltage gain DC-DC converter is simulated using MATLAB/SIMULINK software.

INTRODUCTION DC microgrid innovation is advancing because of the infiltration of conveyed generating sources. DC power generators produce low yield voltage and thus require high effective high increase DC-DC converters to meet the DC load prerequisites. These days, high addition DC-DC converters are utilized in numerous applications other than the sustainable power source transformation, for example, battery reinforcement frameworks for continuous force supplies, high power release light weights for car headlamps, electric pulling forces and some therapeutic equipment [1-2]. In the ongoing past, traditional DC-DC help converter is utilized to step up the voltage. Be that as it may, the voltage weight on the switch is equivalent to the yield voltage. Subsequently, high appraised switch is chosen to meet the voltage weight on the switch that outcomes in high conduction loss [3-4]. Different segregated dc–dc converter topologies are proposed in the writing to accomplish desired high voltage gain .Some of the non-confined high addition converters are cascaded boost  and voltage lift [7-8].Hybrid high gain high power topologies are likewise created [9-10]. In the writing, various non-confined high-gain DC–DC converter topologies with voltage boosting strategies have been talked about, few of them are cascaded boost , quadratic lift , and switched inductor (SI)/capacitor (SC) . In cascaded boost converter, the high-voltage gain has been accomplished with more segments, thereby expanding the system complexity and ABSTRACT Available online at: http://www.ijmtst.com/vol6issue02.html International Journal for Modern Trends in Science and Technology ISSN: 2455-3778 :: Volume: 06, Issue No: 02, February 2020 91 International Journal for Modern Trends in Science and Technology G Bharani and Dr. A Rubymeena, “Design of Triple Switch Double Inductor Based High Voltage Gain DC-DC Boost Converter” results in poor proficiency . In this converter , the level of the voltage stress on the diodes and switches concerning the yield voltage are less. The proposed converter has high voltage gain by choosing appropriate duty cycle for the three switches and by planning legitimate inductor and capacitor esteems. It has the accompanying points of interest: (I) the three switches in the proposed converter works with two diverse duty ratios to accomplish high voltage gain; (ii) the stored inductor energy is provided to the load without extra clamping circuit; (iii) the voltage gain accomplished by the proposed converter is more prominent than the traditional boost converter (iv) diminished voltage stress on the diodes and switches dependent on the rate yield voltage; and (v) the proposed converter is fit for accomplishing high voltage gain without VMC as well as hybrid switched capacitor techniques. II. PROPOSED HIGH GAIN CONVERTER TOPOLOGY Fig. 1 Proposed circuit diagram The proposed triple switch double inductor based high voltage gain DC-DC converter appeared in Fig-1 comprises of three dynamic switches S1, S2 and S3, two inductors L1 and L2, two diodes D1 and D2 and one yield capacitor Co. The switches S1, S2 and S3 work at an switching frequency of fs. The duty ratio of the switches S1 and S2 is D1 and the third switch S3 is D2.The output capacitance Co is adequately large to maintain constant output voltage. Let the number of turns in the two inductors is equal, so that
