Abstract

A novel 50 V, 40 x 80 A multichannel pulse power supply, consisting of 40 numbers of 50 V, 80 A pulsed output channels for biasing pulsed RF amplifiers, is presented in this manuscript. It employs an FPGA based control and protection unit for generating drive pulses of each pulsed output channel as well as for their protection. This control unit has capability to vary the pulse width of drive pulses of pulsed output channels from 150 µs to 2 ms and frequency from 1 Hz to 50 Hz. The PSpice simulation of individual 50 V, 80 A pulsed output channel has been carried out and simulations results are also presented. Efforts have been put to minimize the inductance in the power paths of all the pulsed output channels and maintain synchronism among them. All the output channels have been simultaneously tested on dummy resistive load at 80 A peak current, 2 ms pulse width and 50 Hz switching frequency. The rise time and fall times of output pulses are observed as < 10 µs and pulse droop is observed as < 1%. The jitter between different output pulses is observed as 60 ns.

Abstract

Conversion of Energy plays a crucial role in present-day and requires efficient converter systems. In the conversion of energy process either AC can be converted to DC or DC can be converted to AC. The conversion of energy is done by Power electronic converters which play a key role in photovoltaic systems that are integrated with energy storage systems such as batteries. These converters allow efficient charging and discharging of batteries, voltage regulation, and synchronization with the grid. DC to DC conversion requires DC to DC converters. To obtain the maximum power from the converter the switching of the power electronics device plays a major role by controlling the time duration of the switch and the output power can be maximized. In this work particle swarm metaheuristic algorithm is used to generate the duty ratio and a PWM pulse generator is used to generate the triggering pulses for the switch. A detailed analysis of the ZETA converter is done with PV as input and EV as application. A 5-by-5 PV system with a Zeta converter is simulated in a MATLAB environment. The simulation results show that the ripples in output are minimal which supports the smooth and efficient charging of EV battery which promotes the use of clean energy.

Abstract

In the contemporary era, the global rise of two-wheeler electric vehicles has become pivotal for sustainable development and energy conservation. The necessity for an efficient and effective charger for these vehicles is evident. While numerous two-wheeler electric vehicle chargers are available in the market, this research paper introduces a novel on-board charger tailored specifically for two-wheeler vehicles. The proposed charger integrates totem pole ACDC converter and DC-DC converter to achieve unity power factor and ensure constant current battery charging, thereby enhancing overall efficiency. The incorporation of these converters not only improves charging performance but also facilitates a higher degree of energy conservation. This paper delves into the simulation and analysis of this innovative two-wheeler electric vehicle charger. The use of both converters is instrumental in minimizing harmonics injected into the grid, contributing to enhanced grid compliance. The presented findings suggest that chargers of this nature are poised to gain popularity in future, addressing the growing demand for efficient and sustainable charging solutions for two wheeler electric vehicles.

Abstract

The Internet of Things (IoT) is transforming the agriculture industry and enabling farmers to contend with the enormous challenges they face. Livestock monitoring, conservation monitoring, and plant & soil monitoring are the challenges for which IoT can provide solutions. Innovative IoT applications address agricultural issues, enhancing the quality, quantity, sustainability, and cost-effectiveness of production. Today's large and local farms can leverage IoT to remotely monitor sensors detecting soil moisture, crop growth, pests, and control smart connected harvesters and irrigation equipment. This paper aims to monitor soil parameters such as moisture, temperature, and electrical conductivity, and automate the irrigation process. Decision-making is executed through a microcontroller. Users are notified via android apps when there are deviations from expected values, ensuring system health. Greenhouses are controlled environments for plant growth. The main aim of this paper is to design a simple, low-cost, IoT-based system to continuously monitor and control environmental parameters to achieve optimal plant growth and yield.
