This multipurpose general purpose supply generates as much as 2.5 amps from zero to 20 volts or up to 1.25 amps from 0-40 volts. Current limiting is variable within the entire range for either output options. By Trupti Patil Power Supply Main Specifications: AN IDEAL POWER SUPPLY must provide a voltage that is variable within […]

3 Solid-State Single IC 220V Adjustable Power Supply Circuits
These AC to DC power supplies use a single chip to convert mains 220 V or 120 V input AC into 12 V or 5 V DC without depending on a transformer. Three simple yet efficient 220V single chip based solid state transformerless adjustable solid-state power supply circuits are discussed here. The first one works […]
Adjustable 3V, 5V, 6V, 9V,12V,15V Dual Power Supply Circuit
The purpose of this paper is to detail a variable dual lab power supply circuit which has an adjustable range from 3V, 5V, 6V, 9V, 12V, and 15V or even more at an output current rate of 1 amp. Written By: Dhrubajyoti Biswas The Dual Power Supply Concept In regard to positive volt it is […]
Adjustable CDI Spark Advance/Retard Circuit
In this post we’ll learn about a simple circuit which allows a manual adjust feature for the spark timing of a motorcycle’s CDI either to achieve an advance ignition, retarded ignition or simply a normal timed ignitions. After a comprehensive study regarding the subject I was apparently successful in designing this circuit which can be […]
How to Modify SMPS for Adjustable Current and Voltage Output
This article discusses a method through which any ready made SMPS can be converted into a variable current smps circuit using a few external jumper links. In one of the previous articles I have explained how to make a variable voltage SMPS circuit by employing a simple shunt regulators stage, in the present hack also […]
Adjustable 0-100V 50 Amp SMPS Circuit
The high power adjustable switching power supply is perfect for the purpose of laboratory work. The topology used to design the system is switching topology – half controlled bridge. Written and Submitted by: Dhrubajyoti Biswas Warning: The following circuit design works with a direct 220 V Mains AC without any isolation at the input side, […]
