“…This shows that proposed converter require a magnetic core of lower size (24% lower than that of [5]. Similarly, magnetic core size of the proposed converter is found to be 31%, 24% and 12% lower than that of the converters presented in [10][11], [25][26] and [3] respectively. As given in Table I, component count of the proposed converter is slightly higher than [3], [5], [25] and [26].…”

“…To improve the power density of a converter, size of the magnetic components need to be reduced. In conventional high voltage gain coupled inductor converters [10][11], coupled inductor transfer its energy to output during only one switching state (either on or off state). Hence to obtain high voltage gain, coupled inductor need to store high amount of energy which leads to the selection of large magnetic core.…”

“…Voltage spike on the switches due to the coupled inductor's leakage energy is the main concern of these converters. Lossless passive clamp [4], [9] or active clamp [10], [11] technique is used to limit this voltage spike on the switches. In [9], a boost converter is integrated with a flyback converter (Integrated boost converter) to obtain high voltage gain.…”

A non-isolated soft switched integrated boost converter having high voltage gain is proposed for the module integrated PV systems, fuel cells and other low voltage energy sources. Here a bidirectional boost converter is integrated with a resonant voltage quadrupler cell to obtain higher voltage gain. The auxiliary switch of the converter, which is connected to the output port acts as an active clamp circuit. Hence ZVS (zero voltage switching) turn on of the MOSFET switches are achieved. Coupled inductor's leakage energy is recycled to the output port through this auxiliary switch. In the proposed converter, all the diodes of the quadrupler cell are turned off with ZCS (zero current switching). This considerably reduces the high frequency turn off losses and reverse recovery losses of the diodes. ZCS turn off of the diodes also remove the diode voltage ringing caused due to the interaction of the parasitic capacitance of the diodes and the leakage inductance of the coupled inductor. Hence to protect the diodes from the voltage spikes, snubbers are not required. The voltage stress on all the MOSFETs and diodes are lower. This helps to choose switches of low voltage rating (low RDS(ON )) and thus improve the efficiency. Design and mathematical analysis of the proposed converter are made. A 250W prototype of the converter is built to verify the performance.

“…Therefore to overcome the above problems many methods such as use of resistor capacitor diode, converters operating in discontinuous conduction mode [3][4] a passive lossless clamped circuit and use of additional snubbers had been suggested to reduce the voltage stresses of switches and to retrieve the energy trapped in the leakage inductor. A soft switching method is also used in dc-dc converter for high efficiency and to increase the power conversion density and high efficiency [5].…”

High voltage gain dc-dc converters plays an major role in many modern industrialized applications like PV and fuel cells, electrical vehicles, dc backup systems (UPS, inverter), HID (high intensity discharge) lamps. As usual boost converter experiences a drawback of obtaining a high voltage at maximum duty cycle. Hence in order to increase the voltage gain of boost converter, this paper discusses about the advanced boost converter using solar power application. By using this technique, boost converter attains a high voltage which is ten times greater than the input supply voltage. The output voltage can be further increased to more than ten times the supply voltage by using a parallel capacitor and a coupled inductor. The voltage stress across the switch can be reduced due to high output voltage. The Converter is initially operated in open loop and then it is connected with closed loop. More over the fuzzy logic controller is used for the ripple reduction.

“…Due to the drawbacks of the previous topologies coupled-inductor based dcdc converters are employed. [14]- [16].This topology increase the voltage gain ,reduces the voltage spikes across the switch and also easy to adopt the ZVS(Zero Voltage Switching) for main switch, hence switching loss can be reduced [18]- [20]. By use of coupled inductor in the input side of converter input current ripple is very more, as a result conduction loss of switch increased to more.…”

This paper proposes the novel three phase non isolated high voltage gain boost converter using coupled inductor. The proposed converter consists of coupled inductor based three phase switch cell network, voltage multiplier cell. The high voltage gain is obtained by recycling stored energy in inductor and voltage multiplier cell. The reduced current stress of main switch was obtained by this proposed three phase configuration. Hence conduction loss of three phase boost converter reduced compared to other conventional boost converter. The voltage stress across the switch is reduced by introduction of voltage multiplier at output. This novel three phase configuration reduce input current ripple by use of three phases at input side. The detailed analysis of proposed three phase interleaved boost converter was done by using simulation MATLAB/simulink simulation. The simulation results are presented to analyze the performance parameters of proposed converter.
