build a power supply using a dc adapter
Many different devices require DC power and thus need an I.T.E power supply. I.T.E stands for "Information Technology Equipment." An example of such a device is an iPod speaker system that is no longer functional, which originally came with a...
Flyback Power Supply Powers Subscriber Line Interface Circuit
Cable and xDSL modems are increasingly popular, leading to a need for designs that interface with existing telephones at subscriber locations. The subscriber line interface circuit (SLIC) within the modem must ring the phone and provide loop current during conversations....
Switching Voltage Regulators-Step up Step down and polarity invert
Switching voltage regulators include step-up, step-down, and polarity-inverting configurations, along with their working principles and circuit diagrams.
Switching voltage regulators are essential components in modern electronic circuits, providing efficient voltage conversion. These regulators can be categorized into three main types: step-up...
Universal Laboratory Power Supply Circuit
The design's value is derived from the use of IC1, an LM317HVK adjustable series-pass voltage regulator, which provides broad-range performance along with voltage-setting and current-limiting functions. The input to IC1 is sourced from the output of BR1, which is filtered...
Easy exchange of magnetic saturation voltage regulator circuit
Easy exchange of magnetic saturation voltage regulator circuit
The magnetic saturation voltage regulator circuit is designed to stabilize output voltage levels by utilizing magnetic saturation principles. This circuit typically employs a magnetic core, which operates in saturation to regulate voltage,...
Common Hot-Lead Regulator
This circuit derives 5 V DC from 2 AA cells, even at their end-life voltages of 1.05 V, and is approximately 80% efficient, providing 5 V at 4 mA from 2.1 V at 11 mA. IC1 is manufactured by Maxim...
Output sampling winding isolated switching power supply
The diagram illustrates the output sampling winding of an isolated switching power supply. In the diagram, T represents a high-frequency transformer; N2 denotes the self-oscillation positive feedback winding; N3 is the error amplifier; VTS is the winding that provides the...
90Vrms voltage regulator
The circuit is an open-loop RMS voltage regulator designed to deliver 500 watts of power at 90 V RMS, maintaining good regulation within an input voltage range of 110-130 V RMS. When the input voltage is applied, capacitor C1 charges...
Build A 10 Amp 13.8 Volt Power Supply
Sometimes amateurs like to home-brew their power supplies instead of purchasing one off the shelf at any of the major ham radio retail dealers. The advantage to rolling your own power supply is that it teaches us how they work...
