This document presents a multi-output power supply circuit. The circuit utilizes the secondary winding of a transformer and incorporates four voltage regulators: 7812, 7805, 7905, and 7912, providing independent output voltages of +12V, +5V, -5V, and -12V, respectively. Each output...

markII

The following circuits are presented in a logical order from initial power-up to the additional features incorporated at the end of the project. A less organized version of the Mark II design exists, but this is the sanitized and organized...

Visible-red-continuous-laser-gun

Q1 and Q2 control the primary windings of transformer T1 using a square wave signal, the frequency of which is determined by the magnetic properties of the transformer. Diodes D1 and D2 serve as base return paths for the feedback...

Simple-power-supply

This power supply provides both +9 V and -9 V outputs to replace two 9-V batteries. The rectifier circuit consists of two separate full-wave rectifiers, each connected to the secondary winding of the transformer. The first full-wave rectifier, made up...

Capacitor Box Circuit

This is the discharging circuit. The red lines indicate the flow of energy from the capacitors to the terminals when the switch is in the upward position. The circuit is complete due to the connection of the terminals by Ni-Chrome...

power supply Inductive choke with bypass capacitors

An inductor is used in series with a decoupling capacitor, forming a series LC circuit. One of the characteristics of LC circuits is their resonant frequency. A model of this LC circuit was created with a purely resistive load to...

High-performance power supply LM334
