scholarly journals Women Safety Dress using Stun Gun Technology

The ultimate aim of introducing this paper is to control or prevent the crime against them. We propose a stun gun technology-based women safety dress with GPS. This method consists of a system that provides physical security in the case when the women are harassed or whether she is in trouble. In this paper, we proposed an ATMEGA controller and an android application in which both the device and mobile phone are synchronized using the ESP module. This paper will prove to be very useful in saving lives as well as preventing atrocities against women. This system uses a panic key, a boost converter and a GPS module which provides the location of a woman who is in trouble and the stun gun technology which will provide physical protection to the women. If the panic key is pressed, it turns on the system by sending an alert message to the woman’s relatives via android application. The kit is also be accessed by the parents or relatives via the IoT module. At the instance, whenever the panic key is pressed, it provides the high voltage shock pulse to a stranger via the boost converter.

High step-up DC-DC converters are necessary in photovoltaic energy generation, due the low voltage of the panels source. This article propose the Doubler Output Coupled Inductor converter. This converter is based in boost converter and utilize switched capacitors and a coupled inductor to maximize the static voltage gain. The converter achieve a high voltage gain with low turns ratio in the coupled inductor and an acceptable duty cycle. Can highlight the converter utilize low number of components and have low voltage and current stresses in semiconductors. To validate and evaluate the operation of the converter a 200W prototype is simulated.

AbstractHigh switching frequency and high voltage gain DC-DC boost converters are required for electric vehicles. In this paper, a new high step-up boost converter (HSBC) is designed for fuel cell electric vehicles (FCEV) applications. The designed converter provides the better high voltage gain compared to conventional boost converter and also reduces the input current ripples and voltage stress on power semiconductor switches. In addition to this, a neural network based maximum power point tracking (MPPT) controller is designed for the 1.26 kW proton exchange membrane fuel cell (PEMFC). Radial basis function network (RBFN) algorithm is used in the neural network controller to extract the maximum power from PEMFC at different temperature conditions. The performance analysis of the designed MPPT controller is analyzed and compared with a fuzzy logic controller (FLC) in MATLAB/Simulink environment.
