“…Finally, the comparison of the MBDC converter with other MICs has been carried out based on several parameters like total part counts in the converter, the efficiency and voltage stress of the converter and are illustrated in Table 4. A performance comparison of the MBDC converter has been carried out with three other converters proposed in the literature [6,13,24]. The output voltage of the converters due to the variation in duty ratios d1 and d2 is analyzed in a detailed manner, and the results are given in Figure 15.…”

Abstract:A novel modified bridge-type dual input DC-DC converter, which is proficient for integrating distinct V-I characteristic sources such as solar-PV, wind, etc., and storages including battery, ultracapacitor, fuel cell, etc., is proposed in this paper. Three modes of operations such as boost, buck, and buck-boost are possible using the same structure of the converter, and the converter can operate even with the failure of any one of the input energy sources to deliver power to the load. A software simulation and experimental realization of the converter have been carried out for the buck, boost, and buck-boost operations. The voltage and current stress analysis of the power switches available in the converter have been carried out for the better selection of power switches. A simple power control strategy is proposed for the steady state, and dynamic performance analysis of the converter and performance comparison with existing converter topologies have been carried out based on the different parameters like duty ratio, efficiency, etc. The performance comparison shows that the proposed converter has high voltage gain, low voltage stress, reduced part counts and high efficiency.

“…Several MDC topologies for the applications like renewable energy integration, electric vehicle, etc., are reported in [14]- [17]. The idea of a high step-up DC-DC converters for solar PV application is presented in [18]- [19]. The converter has lower voltage stress on switches, but for n-input mode, it requires n switches and n inductors which make the system complicated and expensive.…”

Power electronic interface has reached a new level in the area of hybrid energy integration nowadays. The existence for the concept of hybrid energy integration is truly questionable without a proper power electronic interface. In this paper, a modified dual input DC-DC converter which is capable of incorporating two distinct V-I characteristic sources such as solar-PV, battery, fuel cell, etc., is proposed. The converter has the ability to operate in both unidirectional and bidirectional mode with buck, buck-boost and boost operation. The software simulation of the proposed converter has been conducted in MATLAB/Simulink platform in a detailed manner and an experimental prototype of the propsed converter has been built to validate the simulation results.

Email: sivanuday@gmail.com INTRODUCTIONThe electricity demand is drastically increasing as a result of massive increase in the population and industrial growth. Conventional energy generation based on fossil fuels and other sources are excessively used to satisfy the increasing power demand. But in the current scenario of electric power generation, the rapid depletion of fossil fuel and the critical environmental issues due to the usage of these conventional energy sources made the researchers to think about the alternatives. Hence the practice of using the nonconevntional energy sources such as solar-PV, wind and storages like the battery, fuel cell and ultra-capacitor are started since they are clean and non-polluting in nature. But the stand-alone usees of these energy sources particularly solar-PV and wind is not preferable due to their highly intermittent nature. Hence the idea of Hybrid Energy System (HES) is developed to overcome these issues.The HES is an advanced technology which is proficient in meeting the widely changing rural electricity requirements by the proper incorporation of non-conventional energy sources with same or distinct voltage-current (V-I) characteristics [1]. The powerful realization of the concept of hybrid energy integration is incomplete without a suitable power electronic interface [2]. To accommodate multiple number of energy sources, parallel connected single input DC-DC converters are widely used in the conventional scheme. But high cost, large system complexity and lower efficiency are the major demerits of this method. To cancel out these drawbacks, the notion of multiple input DC-DC converter (MDCs) is developed. Comparatively lower component count, higher efficiency, simple and compact structure are the potential advantages of MDCs. Different MDCs are already reported in the literature [3]- [7]. Most of the MDC topologies are integrating various in...

“…So each of the output voltage levels is less and outputs depend on loads proportion. In [7] a dual input single output is introduced which is extracted from traditional boost and buck-boost converters. This converter has better voltage gain rather than the previously mentioned converters.…”

Abstract:The proposed model of dual output converter is presented based on CUK and SEPIC converters. The dual output of a single input voltage source is useful in various applications, like DC micro grids, Electrical machines, Solar Energy systems. The proposed converter requires less number of inductor and capacitor as it is compared with the separate converter. The proposed converter is useful regarding the different output polarities. In addition, this converter can be used as multiple voltages power supply. The converters analysis is carried out in continuous current mode. The proposed converter is simulated both in open loop and closed loop using MATLAB/SIMULINK model.
