Innovative power electronic converters have emerged because of renewable energy expansion in the past two decades. Direct current DC grids can operate independently or connected to power grids. A DC grid has distributed generation (DG) units, such as solar panels and, fuel cells. It is necessary to have a DC-DC converter in DC grids to raise output voltage. Boost converters have limited voltage gain, and their switching stress is often equal to their output voltage. This work proposes a converter which gives high gain and less stress when compared to other recent converters. At 0.8 duty ratio, this converter produces an elevated gain of 59. An experimental prototype is built for the proposed converter and the results are presented.

<p><span>DC-DC converters are devices which convert direct current (DC) from one voltage level to another by changing the duty cycle of the main switches in the circuits. These converters are widely used in switched mode power supplies and it is important to supply a constant output voltage, regardless of disturbances on the input voltage. In this work, the performance of three different converters such as Single-Ended Primary-Inductance Converter (SEPIC), Luo converter and ZETA converter have been analyzed. Further, the parameters values such as ripple voltage, switching losses and efficiency of the proposed three different converters were compared with each other. Also, the simulation work has been carried out using MATLAB/SIMULINK software. From the comparison of obtained results, it is observed that the ZETA converter has high significance than the SEPIC and Luo converter.</span></p>

“…Need of perfect output at the DC stage during continuous conduction requires low THD and high input power factor at AC input side [27]. Luo topology of AC to DC conversion is used for power quality improvement with hysteresis controller to achieve high power factor along with supply current harmonic distortions of less than 5% [13]. THD analysis for various load conduction of AC to DC three level converter with a help of different controller tuners such as PI, Fuzzy tuned PI controller, the comparative results for each controller provides optimised result [11].…”

This paper provides a power quality analysis of single phase full bridge rectifier fed DC motor drive. A single phase full bridge rectifier is generally used in low voltage distribution system. It is necessary to analyse harmonic level and power factor. Here, DC motor is considered as the rectifier's load. The THD and power factor analysis is done for different loading conditions. The first analysis is based on variation of delay angle and its effect on THD and power factor. The second analysis is based on variation of torque or the changes in mechanical load done in the motor while maintaining the delay angle as constant. These analyses are useful in quantizing the THD and power factor at various conditions. FFT analysis on the input current provides the information about the various harmonics present in the waveform. The overall analysis is done using MATLAB software.
