Series DC power supply
A power supply typically consists of a transformer, rectifier, filter, adjustment components, and reference power supply and sampling circuits. Additionally, it may include overload or short circuit protection devices. The circuit begins with a 220V step-down transformer (T) that converts...
15 V FOR VTVM
A simple rectifier circuit replaces the battery in a vacuum-tube voltmeter (VTVM). It provides good regulation and eliminates the need for frequent battery replacement. The battery should be removed before using the supply. The AC source can be the 6.3-V...
Electronic Transformer Coupled Oscillators
The transformer OCL and capacitor C1 create a tank circuit, which is coupled with sufficient turns to drive the grid in the lower left-hand winding. The output circuit is connected through a separate winding. For optimal waveform characteristics in such...
DIY Circuit Car Battery Charger
This simple circuit consists of a transformer, two diodes, a capacitor, and an ammeter. To charge a battery, connect the positive and negative terminals of the circuit to the corresponding terminals of the battery. When the battery is not charged,...
Voltage Regulators
Until Willow Garage was acquired, there was work as a Web Robotics Engineer. This title reflects a role as a full-stack engineer focused on real-time, distributed robot control. Notable projects include an XML-RPC server and client for Node.js, a deprecated...
Electrical transformer tutorial
Afroman explains the fundamentals of transformer operation, where to purchase step-down mains transformers, and how to safely wire one to mains voltages. The discussion includes both European and North American wiring standards. The presentation concludes with a brief example of...
bjt Low voltage/current power supply for wide range of inputs
A simple low voltage/current power supply that can accept a wide range of input voltages, up to several hundred volts. The input range is specified as 20 to 160V DC, with an output requirement of 10V and a maximum current...
Regulated 12 Volt Supply
This circuit utilizes a 13-volt zener diode (D2) for voltage regulation. Approximately 0.7 volts are dropped across the base-emitter junction of the transistors, resulting in a higher current output of 12.3 volts. The circuit is capable of supplying loads up...
Design and making of the stabilized voltage supply of switch
Under the loading condition of the resistance, the output voltage (Uo) variable range is from 30V to 36V, with a maximum output current (Imax) of 2A. When the input voltage (U2) changes from 15V to 21V, the voltage regulation factor...
