To extract regulated power supply from the inputs of unregulated conditions, the zeta converter topology is the major application in the power electronics current mode operation. Zeta convertor can interfaced for high frequency application with a less switching stress and also it obtains regulated output voltage from the given input voltage which varies below and above output voltage, When compared with buck, boost, buck-boost and cuk converter, it gives non pulsating current with reduced settling time with adaptability. For different duty cycles and constant switching frequencies, the zeta converter with resistive load gives better results for buck and boost application.

The present invention proposed in this paper is a multi-role UAV with in-built Rover for Disaster Rescue Management (DRM) operation. As we know, Disaster Rescue operation are very complex, difficult and time consuming. The loss of human life during such operations after a disaster has been an area of concern for various organizations. In places with heavy rainfall and bad weather, DRM operation becomes an uphill task. The proposed invention is a hybrid UAV with an in-built Rover capable of image capturing with live feeds to the remote central station and thermal image capturing capability. The system is built such that, in case of heavy debris and landslide where Rover operation can’t be initiated at starting due to blockage of path for rover to move, the UAV is initiated and the Rover takes over when is clear path is visible. The device is equipped with GPS (Global Positioning System) with sends the location to the central system or remote command Centre whenever the image capturing system detects a heat signature through thermal imaging. In case of GPS failure, the system is developed with secondary back up which drops a sensors marker which the remote unit can track. The system proposed here is developed with an aim of reducing the loss of human life and increase effective DRM operation which reduces the time taken for search and rescue operation.
