Abstract: DC Voltage boosting is essential for many applications. Several techniques and topologies have been developed to produce high DC voltages. The Transformerless technique of producing high voltage DC is also been developed however there are certain inherent drawbacks in the developed techniques. This paper introduces the analysis and design of SEPIC (Single Ended Primary Inductance converter) topology based high voltage DC-DC Boost converter with single and two stage added boost converter, to achieve high boost ratio in the range 10 to 50 with low input voltage ranging from 12V-15V. The paper describes the operation of SEPIC topology converter and compares with other boost topologies. The converter is operated in open loop for high step up without the use of transformer thus reducing the magnetic leakage and associated losses. The designed SEPIC converter is simulated in PLEC’s software with ideal operating conditions and desired output of 200V with low inductor current ripple is obtained.
Keywords: Current Ripple, SEPIC-Single-Ended-Primary- Inductance Converter, Transformer less.
