“…Hence, a non-isolated dc-dc converter can thus be utilized to reach a high gain of voltage while easy circuit and minimum cost [18]. Non-isolated high gain converters provide the following, Voltage Multiplier (VM) cell [19], Switched Capacitor (SC) [20,21], the quadratic boost [22], cascade boost [23]. Thus, the resonant inductor is coupled to the SC converter to neglect the problem of diode recovery and to restrict the maximum current [24].…”

Renewable electricity options, such as fuel cells, solar photovoltaic, and batteries, are being integrated, which has made DC micro-grids famous. For DC micro-grid systems, a multi input interleaved non-isolated dc-dc converter is suggested by the use of coupled inductor techniques. Since it compensates for mismatches in photovoltaic devices and allows for separate and continuous power flow from these sources. The proposed converter has the benefits of high gain, a low ripple in the output voltage, minimal stress voltage across the power semiconductor devices, a low ripple in inductor current, high power density, and high efficiency. Soft-switching techniques are used to realize that the reverse recovery issue of the diodes is moderated, the leakage energy is reused, and no new scheme is appropriated. To reduce conduction losses, minimum voltage rating MOSFETs with a low ONresistance can be utilized. The converter can supply the required power from the load in the absence of one or two resources. Furthermore, due to the high gain of boosting voltage, the converter works in an Adaptive Neuro-Fuzzy Inference System (ANFIS). The operation principle, steady-state analysis of the proposed converter, is given and simulated utilizing MATLAB/Simulink simulation software.

“…Moreover, many applications do not need electrical isolation. The widely used method to enhance the voltage gain is voltage multiplier cell (VMC) based converters [3][4][5][6][7][8]. These converters make use of switchedcapacitor (SC) and/or switched inductors (SL) cells; these VMC cells are applied to the conventional converters to increase the voltage gain.…”

This paper introduces the concept of inductors asymmetric input voltage to derive a new high voltage gain converter. The proposed converter has continuous input, positive output, and high-power density features suitable for renewable energy applications. The operating principle, steady-state performance, practical voltage gain, small-signal analysis, and efficiency of the converter are presented in this work. A comprehensive comparison is made with the high voltage gain converters available in literature in terms of component count, voltage gain, effectiveness index, voltage and current stress on the power devices, per unit switching device rating, and other features like output polarity and availability of common ground. The proposed topology possesses a higher effectiveness index and lower switching device power rating (SDP), resulting in a good form factor. To validate the performance of the proposed converter, the experiments are conducted on the 150 W laboratory prototype, and corresponding results are presented in this work.INDEX TERMS DC-DC converter, high voltage gain, quadratic converter, steady-state analysis, voltage stress.

LED lighting is a lamp that is to be provided using AC voltage. The voltage of 220-240 volts is the working voltage of the LED lighting. Under certain conditions, the driver LED light can also be activated using a DC voltage at a voltage of 120-125 volts DC. In solar cell power plants, storage of electrical energy from solar cells generally uses 2-12 volt batteries. To turn on the LED lighting utilizing the input voltage from the solar cell battery, equipment is needed that can increase the voltage level greater than 120 volts DC. DC-DC converters can be utilized to raise a low voltage level to a higher voltage level. In this paper, the boost converter as a DC-DC converter and the Cockcroft Walton method is used as a power supply for LED lighting in households. After testing, the output voltage from DC to DC is 119.98 volts with a 5-watt lamp loads with a current of 0.0389 A, while the input voltage is 3.7 volts and a current of 1.49 amperes with an efficiency of 84.5% and is feasible to be implemented.
