Drunk driving is the only one reason behind most of the unnatural deaths in the world. In this paper, Novel based IOT (Internet of Things) module is proposed to protect the people from unnecessary deaths caused by road accidents due to drunken driving. The Proposed system makes use of the Internet of things (IOT) device as Raspberry Pi 3 model B as a core. It mainly includes Touch sensor, alcohol concentration detection sensor, Facial recognition, Heart beat rate, to safeguard the drowsy driver. We use different type of safeguarding things such as GPS module, Triggering an alarm and Automatic ignition off etc.

Hampel estimator is proposed to robustify the frequency estimation. It was observed that the average frequency estimation error becomes zero when a (2/3) phase interval was considered to calculate the signal difference. Numerical simulation results show that the frequency estimation error when impulsive noise is added to the input data approaches the Cramer–Rao bound. Further, the effect of harmonic components on the frequency estimation error minimization is also considered, when the phase interval is close to (2/3) and the total number of data sample covers several signal periods or truncated close to an integer multiple of the signal period. Keywords- Cramer–Rao bound; M-estimator; frequency estimation; least-squares method.

Renewable energy sources such as photovoltaic (PV) cell and fuel cell are characterized by low voltage and high current output and have strict current ripple requirement. Hence as an important power electronic interface DC-DC converter plays vital role in distributed generation (DG) system/hybrid system to have lower input current ripple and high output DC link voltage. Therefore, in this work, it is aimed to develop a high gain high efficiency DC-DC converter as a power electronic interface for a renewable energy sources. A zero-voltageswitching (ZVS) dc–dc converter with high voltage gain is proposed. It consists of a ZVS boost converter stage and a ZVS half-bridge converter stage and two stages are merged into a single stage. The ZVS boost converter stage provides a continuous input current and ZVS operation of the power switches. The ZVS half-bridge converter stage provides a high voltage gain. The principle of operation and system analysis are presented. Theoretical analysis and performance of the proposed converter were verified on a 100 W experimental prototype operating at 108 kHz switching frequency. Keywords: Boost converter, coupled inductor, high voltage gain, reverse recovery, zero-voltage switching.
