Designing Square Wave Inverter for UPS - Part 06/17

Square Wave Inverter Block Diagram The square wave inverter is easy to design and suitable for less sensitive electronic devices. For more sensitive electronics, the supply from square wave inverter can result into noise. In this tutorial, a square wave inverter is designed which will input power from a battery and output a square AC waveform. An Inverter should generate an AC signal at the output but that signal is not necessarily an exact sine wave.
 
A square wave can also be considered as an AC signal which can be used to drive less sensitive AC devices.

Keypad controlled and Industrial Gas Monitoring Wireless Robot Circuit SetupThis project demonstrates the use of xbee as the transceiver where the robot is controlled by keypad and amount of gas is measured wirelessly through the xbee. The robot can be moved to the place within the range OF 30m (indoor) or 100m (outdoor) to monitor the amount of gas present in air.

The people only just need to operate the robot using the keypad in the receiver side, where humans no need to involve in entering to the place to measure some poisonous gas.

This project demonstrates the use of xbee as the transceiver where the robot is controlled and distance is measured wirelessly through the xbee. The robot can be moved to the place within the range OF 30m (indoor) or 100m (outdoor) to measure the any distance.

The person only just need to operate the robot using the movement joystick in the receiver side, where person no need to move from the place to measure the distance with his tape.

In the previous tutorial, the Constant Current (CC) Source of 60 mA and Constant Voltage (CV) Source of 4.2 V were designed using LM317 voltage regulator IC. The constant current source is to be used for constant current mode of the battery charging while the constant voltage source is to be used for constant voltage mode of the battery charging. During the designing of constant current source and the constant voltage source, testing a Li-ion battery before charging it was also discussed. Check out the previous tutorial “Basics of Li-ion battery charging” for learning about the basics of Lithium ion batteries, their charging methods and topologies.

AVR Atmega 32 based Alcohol and Smoking Detector Circuit Smoking and alcohol are hazardous to health. Also, the consumption of alcohol is one of the reasons behind many anti-social incidents. That is why, smoking and consumption of alcohol is prohibited in many areas like it is prohibited in schools, colleges, hospitals and public transport like buses and trains. In fact, these kind of activities must be prohibited in all kind of public places. Despite rules of prohibition, there are many incidents when people are found not abiding the rules. In such case, for law enforcement, there must be some system to detect infringement of such laws and the authorities must be sent an alert at time.
 
In this tutorial, an electronic system for the same has been designed.

Hand Gesture Controlled Wireless Robot

The wireless robots are controlled in many ways. Usually, these robots are controlled with the help of a remote control which connects with the robot via Bluetooth, Wi-Fi or RF interface. The remote control has physical buttons to move the robot in different directions.
 
The use of a remote control having buttons to control a robot has a drawback when the robot needs to be controlled instantly and precisely. It involves delay due to the response time of the human handling the remote control. The response time in controlling the robot can be reduced by providing some sort of advanced human interfaces like controlling the robot via gestures, eye movements or brain waves.

Arduino based Autonomous RobotAn autonomous robot is a robot that is capable of moving on its own in an unknown and unstructured environment. An autonomous robot is equipped with software intelligence to sense its environment, detect obstacles in its path and move around an unknown environment overcoming the obstacles.

There are many robotic designs that are employed in designing of autonomous robots. These designs are usually developed considering the physical environment in which the robot has to be deployed. There are autonomous robots like snake robots, walking robots, autonomous drones and autonomous robotic cars or rovers.

Battery linear charger real time circuit arrangementIn the previous tutorial, the basics of Lithium ion batteries were discussed. Also, it was discussed how it is important to handle these batteries with care. as mentioned in the previous tutorial, that Lithium ion batteries need to be charged using CC-CV method, in this tutorial, a Li-ion battery charger for a single-cell Li-ion battery of nominal voltage 3.7 V will be designed. 
 
There are charger modules available in the market which can be used to charge the Li-ion batteries. In this tutorial, a charger built using the basic electronic components including Linear Regulator will be designed from scratch. The charger circuit will be customized as per the battery specifications and the charging requirements.

Designing 12V Lead-Acid Battery Constant Voltage Limited Current Charger for UPS

18-0-18V Step down transformerIn this tutorial, a constant voltage charger for the 12V lead acid battery will be designed. The lead-acid batteries can be charged in different ways or modes. In this tutorial, a constant voltage charger will be designed for charging the lead-acid battery. The battery is required to be supplied limited current which saturates once the peak terminal voltage is achieved in the charging process.
 
Depending on the per cell voltage of the 12V battery, the maximum rated voltage of the battery varies from 13.5 V to 14.6 V. In this tutorial, the charger circuit is designed for charging a lead acid battery having peak terminal voltage of 14.4 V.
