This paper proposes a single-switch converter with high step-up gain and low diode voltage stress, suitable for green power-source conversion. By employing a coupled inductor and switched capacitor, the proposed converters achieve high step-up conversion ratio without adopting extremely high duty ratio or high turns ratio. The voltage spike that occurs on the power switch is alleviated, which allows a low-voltage-rated power switch with low R DS(ON) to be adopted, thus reducing the conduction losses. Because the energy of the leakage inductor is recycled, the efficiency is improved. In addition, all diodes' voltage stresses are lowered and are the same, so the selection of power diodes is convenient. Finally, a 300 W prototype circuit with an input voltage of 24 V and an output voltage of 400 V is implemented to verify the performance and functionality of the presented converter. Moreover, the measured highest efficiency is 95.4%.

“…Consequently, the conversion efficiency is degraded and the electromagnetic interference (EMI) problem is severe under this situation. To achieve a high conversion ratio and to avoid operating at extremely high duty cycles, many nonisolated converter topologies have been studied [1][2][3][4][5][6][8][9][10][11][12][13][14][15][16][17][18].

High step-up voltage gain nonisolated DC-DC converter have attracted much attention in photovoltaic, fuel cells and other renewable energy system applications. In this paper, by combining input current ripple-free boost cell with coupled-inductor voltage-doubler cell, an input current ripple-free high voltage gain nonisolated converter is proposed. In addition, passive lossless clamp circuit is adopted to recycle the leakage inductor energy and to reduce the voltage spike across the power switch. By utilizing voltage-doubler cell consisting of diode and capacitor, the voltage stress of switch is further reduced and the resonance between the leakage inductor and the stray capacitor of the output diode is eliminated. A low switch-on-resistance low-voltage-rated MOSFET can therefore be employed to reduce the conduction loss and cost. The reverse recovery loss of output diode is reduced, and the efficiency of converter can be improved. Furthermore, the proposed converter can achieve nearly zero input current-ripple and make the design of electromagnetic interference (EMI) filter easy. Steady state analysis and operation mode of the converter is performed. Finally, experimental results are presented to verify the analysis results of the proposed converter.

Recent developments in drives have produced high step up converter based DC-AC converters applied to induction motor drives. High step up converter and inverters find their way between PV and SPIM. This paper deals with High Step-up Converter -Inverter Based Induction Motor Drive (HSCIBIMD), with various levels of solar irradiation .The objective of this work is to minimize the harmonic content in the armature current of HSBIMD system. The output of PV is stepped up using high step up converter, inverted and is applied to the induction motor. This HSCIBIMD system is designed and simulated using MATLAB/simulink and tested using PIC. The hardware results are compared with the simulation results. The results indicate that the harmonics in the load current are minimum. Analysis, simulation results and experimental results are presented in detail.Keywords-High step up converter-inverter based induction motor drive Photo Voltaic; Voltage Source Inverter; Total Harmonic Distortion. INTRODUCTION Power generation from renewable energy sources become popular now-a-days, due to the energy crisis, environmental pollutions and depletion of fossil fuels. Among all the renewable energy sources such as wind energy, fuel cells, tidal energy, etc, Power generation from solar energy using (PV) system has received great attention, in research.[1]- [4]. The PV panels convert light energy into electrical energy and generated low output voltage. Therefore the PV system employs high step-up converter inverter system to transform electrical power to the load or grid [5]. The conventional boost conversion and flyback converts can step up the voltage, but with low efficiency, due to parasitic parameters or leakage inductance. High efficiency of the system can be obtained by having extreme duty cycle and high turns ratio, but results in large conduction losses, diode reverse recovery problems, large leakage inductances and for copper losses in windings respectively. In recent years, many topologies of converters have been developed. [7]- [14]. Among all types of converters, high step-up, DC-DC converter with the inverter improves power-conversion efficiency and provides a stable DC link to the inverter. [15]. Fig.1. shows the block diagram of PV system with PV panel and micro inverter along with a floating active switch is designed to isolate the DC current from the PV panel, when AC module is off grid or in the non operating conditions. This isolation ensures the safe operation of internal components. K.Chigh Tseng et-al presented a high step up converter with voltage multiplier modules in [22],to achieve high step up voltage gain .A novel high step-up DC-DC converter with a switched -coupled inductorcapacitor structure is proposed by Hong chantia et-al in [23]. A DC-DC boost converter step up the DC voltage from the PV system in [24], a DC-DC boost converter of 12V/24V closed loop is used in solar powered LED lighting system [25]. The above literature does not deal with PV based high step up converter, inverter system. The pres...
