X-Y converter family: A new breed of buck boost converter for high step-up renewable energy applications

Abstract

Abstract-A New breed of a buck boost converter, named as the XY converter family is proposed in this article. In the XY family, 16 topologies are presented which are highly suitable for renewable energy applications which require a high ratio of DC-DC converter; such as a photovoltaic multilevel inverter system, high voltage automotive applications and industrial drives. Compared to the traditional boost converter and existing recent converters, the proposed XY converter family has the ability to provide a higher output voltage by using less number of power devices and reactive components. Other distinct features of the XY converter family are i) Single control switch ii) Provide negative output voltage iii) Non-isolated topologies iv) High conversion ratio without making the use of high duty cycle and v) modular structure. XY family is compared with the recent high step-up converters and the detailed description of XY converter family and its topologies are presented. The simulation results are provided and it confirms the feasibility, functionality and validity of the concepts of the proposed XY converter family.

“…Nowadays, DC-DC Multilevel Boost Converters (MBC) is addressed in literature to overcome the drawback of above discussed converter using diode and capacitor networks [10]- [14]. In [11], inverted high voltage with conversion ratio 20 and 40 at duty cycle 75% is accomplished using Nx and 2Nx MBC.…”

“…The multilevel DC-DC converter topology discussed above gives a suitable way to accomplish high voltage however, required substantial number of diode and capacitor. In [14], X-Y converter family is proposed to attain high voltage conversion ratio by utilizing least number of components. In view of the arrangement of inductor, total sixteen converter topologies are proposed in X-Y family.…”

Multistage DC-DC Step-Up Self Balanced and Magnetic Component Free Converter for Photovoltaic Applications—Hardware Implementation

“…Unluckily, large reactive network follows the limited switching frequency which is employed to protect the ripple condition of voltage and current [17]. Traditional Buck-Boost converter is not reliable due to discontinuous input current, which results in low utilization of input source [13], [15]. By increasing the switching frequency of the converter, the problem of leakage resistance for certain values of ripple can be overcome.…”

“…The drawback of the PV-MSIS are i) required several DC-DC converter before transfer energy to inverter ii) high cost due to more number of converters and separate MPPT. The output obtained from the photo voltaic cell/array is usually low, so before feeding this voltage to the inverter for practical application purpose, it is needed to be stepped up using conventional DC-DC boost converter [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. With the increase in the duty-cycle of switch and leakage resistance of inductor, the performance of the converter degrades.…”
