When the battery is kept in the discharge state for a long period, irreversible chemical reaction takes place reducing the capacity of the battery so that eventually the battery becomes useless. No protection circuit can stop self discharge of the battery and only trickle charging on compensate for it. Here is a circuit charging reminder for emergency light to inform the user that the battery has discharged itself below the safe level. The discharge characteristics of a dry battery, as supplied by its manufacturer indicate that the battery should not…
The most common source of power supply these days is the AC mains because it is more efficient and economical to generate and transmit AC power. However, DC voltage/current is required for the satisfactory operation of a wide variety of electronics equipment using solid-state devices, such as diodes, transistors, and ICs. But for the operation of most of the electronic circuits, we need d.c power of various ranges. Hence it is necessary to convert a.c. power into d.c. power. For conversion of A.c. power into d.c. the power we utilize…
In this article we are going to learn what is tracking and floating voltage regulator with its key parameters, applications with appropriates comments. At first let’s see what about tracking voltage regulator. Description of tracking voltage regulator In effect, a tracking voltage regulator performs the function of two separate voltage regulators, positive and negative, with but a single adjustment to track both voltages accurately. As shown in figure 1, the voltage from either output to ground will remain the same regardless of load unbalance. Adjustment of the external potentiometer or…
Verified Electronics Projects: Those practicing the art of engineering are concerned with numbers in all phases of their work. One area where the numbers become overwhelming is in the area of electronic projects and their parts. Although the integrated circuit (IC) has been a boon to the electronics engineers/hobbyists, the sheer number of parts almost requires the user of the electronic project to have research assistance as an associate, to be sure all electronic projects are available have been considered for use. Valuable time is often spent poring over the…
Introduction to Offline UPS Circuit We all know that most electrical and electronic appliances are solely powered by the AC supply and the problem arises when the power is cut off in the middle or there is no power at all. In such cases, uninterrupted supplies are what we look out for. This is one of those uninterrupted power supply circuits. The fact that it provides an instant power supply from the batteries than standby generators that take long to operate, makes it more practical. To make the use of…
This project is a low-cost multiplexing system for ten channels. The project 10-channel multiplexer circuit using 555 IC can be used as an add-on device for a single point indicating system. Both auto and manual selection are incorporated with the visual indication of channel number. It is suitable for signals concerning a common line. However, for double-ended signals, the input LOW lines can be made common and the input High lines can be multiplexed. This can be used for thermocouple signals, strain gauges, and any other AC/DC signal in the…
