Adjustable half-wave rectifier charging circuit
The adjustment potentiometer RP is utilized to modify the charging current.
The adjustment potentiometer, designated as RP, serves a critical function in regulating the charging current within an electronic circuit. This component is typically a variable resistor that allows for fine-tuning...
Shortcircuit protected voltage regulator
At this voltage regulator prototype the maximum current, with output shortcircuited it was only 0.5 A, so no overheating occurred. In this DC voltage regulator circuit, T1 is for current limitation. As soon as the voltage on the R2 +...
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...
regulator
Malcolm Moore's schematic is good, but it is insufficient for someone inexperienced with a soldering iron to create anything functional. Specifically, T1 is a coil of some type, but the configuration, as well as the values for Q1 and Q2,...
12-16V-converter
Many devices operate from a car's 12-V electrical system. Some require 12 V, while others need a lower voltage. An automobile battery's output can vary from 12 to 13.8 V under normal circumstances. The load requirements of the device may...
40V dual power supply
This 40V dual power supply circuit was designed to power a 150 Watt amplifier circuit. The transformer T1 steps down the mains voltage, while bridge D1 performs rectification. Capacitors C1 and C2 act as filters, and C3 and C4 serve...
Half-Wave Rectifier Circuit
A circuit that utilizes one cycle of alternating current (AC) to produce direct current (DC). A half-wave rectifier circuit generates DC from either the positive or negative cycle of the AC input, but not both. It is important to note...
How to properly snub transient spikes from a transformer and prevent switch mode power supply burn out
The leads from the transformer to the circuit are quite long (>5m). The 110V side of the transformer has been switched off frequently, which likely caused a spike on the secondary (24V) side. The input pin of the LTC3631 shows...
Negative Voltage Generator Schematic
Most operational amplifier circuits require a dual-polarity power supply - one having +V and -V. However, there are times when a DP supply simply isn't conveniently available. Single-polarity modifications to DP designs often achieve their effect by referencing the input...
