SMPS 2 x 50V 350W Circuit for Audio Power Amplifiers
This article will illustrate a simple procedure to devise an unregulated 50V switching SMPS symmetric power supply of 350W. This unit can be substituted with the standard audio amplifier power supply to reduce expense and also the weight. The proposed power supply works as a half-bridge with no regulation.

How to Make Ultrasonic Directive Speaker Circuit
In this post I have explained the construction of a ultrasonic directive speaker system also called parametric speaker which may be used to transmit an audio frequency over a targeted spot or zone such that the person situated exactly at that spot is able to hear the sound while the person next to him or […]
Modify Human Speech with this Digital Voice Changer Circuit
In this post I have explained a voice modulator circuit which will change or transform an individuals unique voice into a completely new form. The new voice will be different to the original voice tone and unrecognizable. The Circuit Concept The characteristic tone of every individuals voice is specifically unique in all circumstances. How often […]
Music Triggered Amplifier Speaker Circuit
The circuit idea I have explained below enables a power amplifier loudspeakers to switch ON only when there’s an input music available, otherwise it makes sure that the loudspeakers remain shut off. The idea ws requested by Mr. David Alda. Technical Specifications Your site is just awesome. I’m hoping you can post a tweak to […]
Making a Stethoscope Amplifier Circuit
In this post I have explained how to make an electronic stethoscope amplifier circuit for enabling a loud audible reproduction of the heart beats which is being diagnosed. The article also reveals how the same can be applied within a cellphone through a wireless circuit. The idea was requested by Dr. Ankit. Main Requirements The […]
