This work deals with reduction of ripple in the bidirectional DC-DC converter. This Converter has the ability to transfer the energy in both the directions. This converter is designed, modeled and simulated using MATLAB SIMULINK and the results are presented. The Pi-filter is proposed at the output to reduce the peak to peak ripple. The simulation results with R-load and DC-Motor load are presented.

ABSTRACT:In this paper, the design methodologies are used to obtain the multiple outputs of DC-DC converter with a coupled inductor. The proposed system consists of single input of low voltage level, which can be boost into two different voltage levels. In this topology a coupled inductor with only one power switch is utilized for voltage clamping and soft switching operation. The two output voltages in this topology are obtained by limited components. The output voltages obtained are middle voltage and high voltage terminals are taken as power for a dc load applications. This topology is developed for high efficiency power conversion and two different voltages for dc loads. The proportionalintegral derivative (PID) controller is designed in DC-DC converter to reduce the rise time and steady state error, and is modelled using SIMULINK and simulation results are obtained. It is referred as single input multiple output DC-DC converter. KEYWORDS:Coupled inductor, high-efficiency power conversion, single-input multiple-output (SIMO) converter, soft switching, voltage clamping. I.INTRODUCTIONIn recent years the demand of energy is growing, rising the public awareness for environment. To protect the earth from global warming, created demand for the development of clean energy without pollution, have resulted in much of the research work focused on clean energies, such as fuel cell (FC), photovoltaic, and wind energy, etc., Because of the electric characteristics of clean energy, the generated power is critically affected by the climate or slow the transient responses, and the output voltage by load variations are easily influenced [1]- [3]. To ensure the proper operation of clean energy, other auxiliary components, e.g., storage elements, control boards, etc., are usually required. The fuel cell generation is one of the most efficient solutions for environmental pollution. In general various DC-DC converters with different voltage gains are made to satisfy the requirement of different voltage levels, so that the system control is complicated and corresponding cost is more expensive [4]. Here the conventional SIMO DC-DC converter capable of generating buck, boosts, and inverted outputs simultaneously. However, over three switches for one output were required. This scheme is suitable for only the low output voltage and power application, and its power conversion is degenerated because of hard switching operation.Although a multi-output DC-DC converter shared zero-current-switching (ZCS) lagging leg having soft switching property can reduce the switching losses, but it is a three full-bridge converter scheme of more complicated. By this scheme the high-efficiency power conversion is difficult to achieve, and its cost is more expensive [5]-[6]. This paper presents a newly designed SIMO converter with a coupled inductor and uses one power switch to achieve its objectives of high-efficiency power conversion, high step-up ratio, and different and different voltage levels. In SIMO converter the utilisation of a low-voltage-ra...

“…Thus, a bidirectional DC-DC converter which allows transfer power between two DC sources become an important topic of power electronics. The bidirectional DC-DC converter is categorized into an isolated converter [4]- [6] and a non-isolated converter [7], [8].

In this paper, a novel bidirectional DC-DC converter employing soft switching technique was proposed. Compare to conventional bidirectional converters, the main switches of proposed converter are operated without switching losses. Moreover, auxiliary switches are used, and the switches are operated under zero voltage switching (ZVS) and zero current switching (ZCS) condition. To verify the validity of the proposed converter, mode analysis, design procedure, simulation and experimental results are presented.
