DC-DC Switched Inductor Boost Converter for DC Drives Applications

摘要

This paper presents a DCDC Switched Inductor Boost Converter (SIBC) which offers a viable solution for DC drives applications which practices nonconventional energy sources. The proposed SIBC is derivation of conventional boost converter by means of substituting inductor with switched inductor. In SIBC, the two inductors are charged parallelely and discharged in series. The methodology is to achieve higher output voltage in comparison with conventional boost converter which uses appropriate duty cycle. The key merits of proposed topology are an continuous input current, a large conversion ratio without use of extreme duty cycle and transformer. The design of proposed SIBC is planned using single switch, two inductor, four diodes, and single capacitors. With the help of performance equations, the components in the proposed converter are designed. The proposed SIBC converter has rated power 100W, output voltage 160V with input supply voltage 20V. The circuit of proposed SIBC is simulated in MATLAB and simulation result will define the validity of the theoretical design.
