Automatic Switching for Battery USB Power Connection
This is a simple circuit for automatic switchover between battery and USB port. This circuit uses a more general step-up converter architecture.
The circuit designed for automatic switchover between a battery and a USB power source employs a step-up converter...
Regulator circuit silicon resistor formed
The simple voltage regulator circuit consists of a silicon regulator and a resistor. It is designed to rectify and filter DC voltage, as illustrated in the accompanying figure. The voltage regulator is connected in parallel with the load, and the...
Car Battery Failure Detector
A car battery deteriorates in use, and its life seldom exceeds four years. When new, its voltage may drop to only 2V while cranking the engine.
A car battery, typically a lead-acid type, is essential for providing the necessary electrical energy...
Simple Battery Level Indicator
This document presents a circuit diagram for a simple and easy-to-construct battery level indicator. Typically, in mobile phones, battery levels are shown in either dot or bar format, allowing users to easily recognize the battery status.
The battery level indicator circuit...
Problem With Electrical Distribution
A 2005 McGregor 26 sailboat is equipped with a Standard Horizon CP150C GPS unit. After relocating the boat to British Columbia, Canada, the GPS unit failed to power on, despite being brand new and unused by the original owner. The...
12V Analogue Battery Volt Meter
This circuit is used to measure the voltage on a 12V (nominal) lead acid rechargeable battery system. It was specifically designed for use in solar powered systems, but is general enough that it can be used for automotive or other...
how does power supply regulate its
Most power supplies regulate either their output voltage or current at a constant level, depending on the load resistance relative to the power supply's output voltage and current settings. This can be summarized as follows: To accomplish this, most power...
Battery Volt Meter
Battery Volt Meter Circuit Diagram. This circuit is designed to monitor the voltage level in Lead Acid or Tubular batteries. It provides four LED indicators to represent the voltage levels ranging from 9 volts to 14 volts.
The battery voltmeter circuit...
Car battery condition checker
This circuit utilizes an LED and a 4081 CMOS integrated circuit. A variable resistor is employed to adjust the voltage threshold at which the LED activates. The control should be set so that the LED illuminates when the voltage from...
