INTRODUCTION In Today’s Modern technology world the demand for power has become inevitable and the magnitude of power demand has gone to such an extent that such demand is not possible to meet with conventional sources such as fossil fuels which are becoming depleted over the past decades, also with the inventions of portable devices which requires less power than those obtained from grid. Hence power engineers around the world are exploring various other sources such as renewable energies like Solar, Wind, Geothermal, etc. and they also trying with hybrid mixture of these sources. In these various renewable sources, Solar energy is most widely trapped at various parts of world due to rise in global warming over two decades, But the major problem in extracting these energies to the maximum useful power depends on many factors, in which the auxiliary devices and circuits used for trapping these energies plays a crucial role. In Solar power , the main device used to extract the power from solar energy is PV cell or PV array but with major constraints with the materials used in manufacturing these devices , the output power obtained from such devices are limited and the obtained power from PV cell are not flexible to meet the consumer demand . Hence to increase the output limit of such devices and to make them flexible to the consumer demand various electronic circuitry have been implemented with the advancement of power electronics in the field of power system. Thus a DC-DC converter circuit is a major power electronic circuitry which is incorporated in the PV system to increase the output limit of PV cell or PV array. 978-1-7281-7612-3/21/$31.00 ©2021 IEEE 2 M.

DC - DC CONVERTERS A DC- DC converter is a circuit which is being modelled with power electronic switches to increase the output level of a PV cell or PV array and the efficiency of these converter circuits depends on the various factors such as the switching devices used in the circuit, Switching techniques used to switch those devices, MPPT algorithms implemented for switching these devices etc. Besides controlling the output power limit of PV systems, these converters also plays a major role in the various applications in which PV systems are used. The topologies of DC - DC converters widely varies with the request of application and hence they can be designed to meet such suitable demand. Over the last two decades various research efforts were taken on employing an efficient DC - DC converter topologies to meet the application demand. Some designs [1] were employed with galvanic isolation, soft switching capability and wide operation range. To design such a high power, high voltage ratio and high efficiency DAB converter for a wide range of voltage application, the stray inductance and turn ratio of transformer are considered as a two key parameters. Resettable integrators were also included [2] in the control circuit to generate Pulse Frequency Modulation (PFM) which regulates converter to transfer the solar power efficiently in standalone applications. Such converters can regulate both the voltage of the solar panel and the load voltage simultaneously. Need of a bidirectional DC - DC converters has become important in residential photovoltaic power generation systems which provides good electrical isolation. By shifting power devices to the input side high voltage gains can be achieved with a low turns- ratio coupled-inductor. Significantly it can reduce voltage stress on the components even for high- voltage applications, and thus contribute to the component selection of smaller power ratings (i.e., lower costs) [4].The efficiency of such converters for PV systems can further be improved with cascaded structure[5] which produces high quality output voltage with low EMI. The gain of the PV cell system with converter can further be improved by means of coupled inductor [6] with a passive clamp network which also prevents problems such as diode recovery. 201 Authorized licensed use limited to: Univ of Calif Santa Barbara.
