charger
The circuit was constructed on a Vero board and tested with a large electrolytic capacitor in place of a battery. A 500-ohm preset resistor determines the output voltage, while a 47k preset resistor regulates the hysteresis and establishes the voltage...
Automatic Inverter Supply and Mains Supply Changeover Relay
This inquiry has been presented multiple times on this blog regarding the implementation of a changeover selector switch for the automatic toggling of an inverter when AC mains power is available, and vice versa. The system must also enable the...
Inverter 12V DC to 240V DC circuit diagram
This inverter circuit is designed to power electric razors, stroboscopes, flash tubes, and small fluorescent lamps using a 12-volt car battery. Unlike typical feedback oscillator inverters, this design features a separate oscillator from the output stage, allowing for easy frequency...
inverter circuits
Some good inverter circuits I found oscillate at approximately 50 to 60 Hz. They are likely capable of handling up to two amps; any more than that will cause them to automatically shut off. If there are questions, please leave...
Simple Pre-Regulator
There will be many occasions when it is beneficial to utilize the P05 supply module sourced from a higher voltage supply. For instance, this could be advantageous when integrating balanced inputs.
The P05 supply module is designed to facilitate the conversion...
Inverter circuit for florescents
This inverter is very easy to construct, reliable, and even powerful enough to light up a 15W fluorescent tube (if you cool your transistor well). The only hard-to-find piece of this baby is the so-called yellow inverter transformer. It's a...
Simple 100W inverter schematic design
This document provides an explanation of a simple 100-watt inverter circuit using the IC CD4047 and the IRF540 MOSFET. The circuit is designed to be simple, cost-effective, and suitable for assembly on a veroboard. The CD4047 is a low-power CMOS...
Replacing Motorola Batteries
The battery packs were approximately $60 per pair, including a charger and batteries, and feature a three-bar battery gauge. Through experimentation, it was found that a voltage greater than 4.28V activates all three bars, while a voltage above 3.47V activates...
how to convert a 9v battery to 3.7v
A regulator circuit is needed for this DIY project. Familiarity with electronic components, circuitry, the use of a multitester, and a soldering iron is essential. The schematic diagram provided can accept an input voltage ranging from 6 to 24 volts...
