The world will need greatly increased energy supply in coming years because of the rapidly increasing world population and depleting natural resources. For a long time, conventional energy sources have been utilized for power generation, but now it is of great concern that the rapid depletion of conventional sources added with their economic and environmental concerns are incompatible to address issues like growing electricity demand and environmental damages. Utilization of the alternative energy sources is compulsory to minimize the energy crisis around the world. Based on the alternative energy sources, a number of power generation systems have been designed to contribute for the management of optimized energy supply systems. The unpredictable nature of alternative energy sources is their common drawback, and they do not harness usable power for some considerable duration of time over the year. Therefore, trends are in progress to integrate two or more than two of these alternative energy systems to meet the required electricity supply in power generation operations. These systems are designated as hybrid systems and can be grid connected or off-grid depending upon their purpose and mode of fabrication. Off grid hybrid systems are popular for the electrification of the isolated and far-flung areas, where the grid supply is absent. This study mainly focuses on main 10 off grid, bi-source hybrid systems for power generation highlighting their role in energy stability. Systems' hybridization, power generation, energy flow schemes, operation schemes, and storage and backup needs have been addressed thoroughly in this study to provide a handy reference to stake holders for further work in this regime.

The next generation of materials will contain many embedded or auached actuators and/or sensors. They will also contain support electronics including power electronics and a computer processor with a communication network along with the "smarts" to respond to their environment. Current research is also directed toward miniaturization of the components, particularly the sensor and actuators with the idea of incorporating large numbers of actuators and sensors into the material. In keeping with this trend, the electronics should also be miniaturized along with the sensors and actuators. In this paper we discuss miniaturized power converters and power systems with potential applications to materials with miniaturized sensors and actuators.

“…The difficulties in DC/DC converter can be overcome by. using zerovoltage-transition (ZVT) [ 1,2] or active clamping soft-switching techniques [3'4]. Usually the soft switching can reduce loss as up to 1-2%( 51 under same switching frequency, or it can allow the power devices to work at higher switching frequency with the same loss, which is beneficial to fabricate more compact converter operating at higher frequency.…”
