variable voltage and current power supply
An alternative method for utilizing operational amplifiers (op-amps) to regulate a power supply is illustrated below. The power transformer necessitates an additional winding to provide the op-amps with a bipolar voltage of +/- 8 volts. This negative voltage is also...
PERIOD TO VOLTAGE CONVERTER
When the input transitions from low to high, a narrow positive pulse is generated at point A. This pulse results in a -13 V level at point B, which causes diode D2 to turn off. Consequently, the V+ voltage of...
Energy losses in modem
A toroidal transformer (2x12V 15VA) is utilized due to its significantly lower energy losses compared to an E-I core transformer, which was employed in the original mains adapter.
The toroidal transformer is a type of transformer that features a doughnut-shaped core...
Build an Experimenters Power Supply
The incoming AC is routed to the primary terminals of a 12.6-volt transformer. The hot side of the AC is connected through a fuse and a single-pole single-throw (SPST) toggle switch. When the switch is in the OFF position, the...
EI30 Transformer board
Every DAC board and decoder includes a power supply component. The only missing part is the power transformer. A toroidal transformer can be utilized, featuring a power switch and fuse holder mounted on the chassis. This document presents one of...
Triple Power Supply
Inexpensive miniature transformers typically provide one or two secondary voltages, which are sufficient for generating a set of positive and negative supply voltages, as required for operational amplifier circuits. However, if an additional voltage higher than either of the supply...
PF Test Equipment
A transformer ratio-arm bridge circuit is utilized as depicted in the simplified diagram of Figure 1. The circuit comprises a standard reference capacitor (CS) and the insulation under test (CX). A distinctive feature of the circuit is a specialized multi-winding...
6v to 12v converter circuits
A 6V to 12V DC converter circuit is designed to convert a lower voltage of approximately 6 volts to a higher voltage of 12 volts, albeit with a reduced current rating. This inverter circuit can deliver up to 800mA of...
6v to 12v converter
This 6V to 12V converter circuit is made with an IC from SGS with several additional components. The IC is a TDA2003 but it can be replaced with a TDA2002. The cost of building the 6 volts to 12 volts...
