This paper presents an interleaved double dual boost converter (IDDB) used in renewable energy application where high voltage gain is required such as fuel cell or photovoltaic applications, etc. Two types of controllers are applied to this converter, 1) a controller based on Flatness properties for regulating the output voltage (outer loop); 2) a sliding mode controller for inductor current (inner loop). The variation of the input voltage is compensated by trajectory planning process. The validation of the proposed system is done through experimental results.

Consumption of energy is progressively rising at a regular rate. To accommodate the demand for electric supply with the exhaustion of typical resources like fossil fuels, renewable energy sources like solar power, wind farms and fuel cells are preferred. DC-DC multilevel converters with high gain appear a crucial segment of the renewable energy system. When compared with common topologies the multilevel DC – DC converter has low harmonic distortion, less stress in voltage, minimum EMI noise, and a raised efficiency. To use photovoltaic (PV) systems for standalone applications or micro grid applications, the low output voltage should be boosted to a certain level, i.e a 400V micro grid will be fed with a boost converter having 20V input voltage and gain of 20 to have 400 V at its output

Voltage Gain

High gain DC-DC converters are getting popular due to the increased use of renewable energy sources (RESs). Common ground between the input and output, low voltage stress across power switches and high voltage gain at lower duty ratios are desirable features required in any high gain DC-DC converter. DC-DC converters are widely used in DC microgrids to supply power to meet local demands. In this work, a high step-up DC-DC converter is proposed based on the voltage lift (VL) technique using a single power switch. The proposed converter has a voltage gain greater than a traditional boost converter (TBC) and Traditional quadratic boost converter (TQBC). The effect of inductor parasitic resistances on the voltage gain of the converter is discussed. The losses occurring in various components are calculated using PLECS software. To confirm the performance of the converter, a hardware prototype of 200 W is developed in the laboratory. The simulation and hardware results are presented to determine the performance of the converter in both open-loop and closed-loop conditions. In closed-loop operation, a PI controller is used to maintain a constant output voltage when the load or input voltage is changed.

To improve the voltage gain of step-up converters, the cascaded technique is considered as a possible solution in this paper. By considering the concept of cascading two Z-source networks in a conventional boost converter, the proposed topology takes the advantages of both impedance source and cascaded converters. By applying some modifications, the proposed converter provides high voltage gain while the voltage stress of the switch and diodes is still low. Moreover, the low input current ripple of the converter makes it absolutely appropriate for photovoltaic applications in expanding the lifetime of PV panels. After analyzing the operation principles of the proposed converter, we present the simulation and experimental results of a 100 W prototype to verify the proposed converter performance.

In this paper, analysis and experimentation of a fourth order boost converter has been proposed for renewable energy source applications such as solar power. The output of proposed converter is fed to motor load of 220W. The main advantages of this converter are negligible current ripples at both source and load side and higher efficiency as compared to the conventional boost converter. The energy storage elements in circuit are designed and optimized using Bacterial Foraging Optimization Algorithm (BFOA) to solve the contradictory problems of steady state and dynamic performance of the system. The up-down glitch in control to output transfer function of system is reduced with the optimized values of energy storage elements in the proposed converter. Therefore dynamic response of system is analyzed with the designed values of inductor and capacitor. Closed loop control is introduced in the proposed system using proportional integral controller to maintain the output voltage constant when there is any load disturbance in the output side and wide variations in the input voltage. Simulation and hardware results of the proposed converter with input voltage of 60V and switching frequency of 100 kHz are presented.

An increase in demand for renewable energy resources, energy storage technologies, and electric vehicles requires high-power level DC-DC converters. The DC-DC converter that is suitable for high-power conversion applications (i.e., resonant, full-bridge or the dual-active bridge) requires magnetic transformer coupling between input and output stage. However, transformer design in these converters remains a challenging problem, with several non-linear scaling issues that need to be simultaneously optimized to reduce losses and maintain acceptable performance. In this paper, a new transformer-less high step-up boost converter with a charge pump capacitorand capacitor-inductor-diode CLD cell is proposed using dynamic modeling. The experimental and simulation results of the proposed converter are carried out in a laboratory and through Matlab Simulink, where 10 V is given as an input voltage, and at the output, 100 V achieved in the proposed converter. A comparative analysis of the proposed converter has also been done with a conventional quadratic converter that has similar parameters. The results suggest that the proposed converter can obtain high voltage gain without operating at the maximum duty cycle and is more efficient than the conventional converter.
