12V 1A SMPS Power Supply Circuit Design on PCB
The most commonly used of type of power supply circuit is the SMPS (Switching Mode Power Supply), you can easily find this type of circuits in your 12V adapter or Mobile/Laptop charger. In this tutorial we will learn how to build a 12v SMPS circuit that would convert AC mains power to 12V DC with a maximum current rating of 1.
Regulated Power Supply-Block Diagram,Circuit Diagram,Working
Regulated Power Supply – Block Diagram. A regulated power supply essentially consists of an ordinary power supply and a voltage regulating device, as illustrated in the figure. The output from an ordinary power supply is fed to the voltage regulating device that provides the final output.
Switch Mode Power Supply (SMPS) - Design, Buck, Boost
The most common application of an SMPS is the power supply unit of a computer. Switching Mode Power Supply (SMPS) has become a standard type of power supply unit for electronic devices because of their high efficiency, low cost and high power density. The following image shows an SMPS unit from an old desktop computer.

SMPS Welding Inverter Circuit | Homemade Circuit Projects
144 require at least 17.5 V to start. A 12 V power supply has been used and driver circuit does not work. 2. This was my dream project since last 2 yrs and I must say that care is required in each and every stage, driver circuit, 18 V power supply, IGBT mounting, cooling, snubber, output diodes mounting and cooling.
Designing Simple Power Supply Circuits | Homemade Circuit
Making a Fixed 12V Regulator Circuit. In the above diagram we can see how an ordinary 7805 regulator IC could be used for creating a fixed 5V regulated output. In case you wanted to achieve a fixed 12V regulated power supply, the same configuration could be applied for getting the required results, as shown below:
Simple Delay Timer Circuits Explained | Homemade Circuit
Power supply for this circuit is 12V (because I am using 12V pump). The input is from an IR obstacle avoidance sensor that will produce 0V when detecting hands and 12V in normal condition. The function is as following: 1. Pump is in standby mode. 2. When detecting hands, pump is activated immediately and running in 2 seconds. 3.
Modifying a Chinese power supply to provide a variable voltage
After this page was posted on Hackaday, a commenter pointed out that 7 is actually a standard power supply voltage! I never knew this, so I was only searching for 5V, 12V, 24V supplies. Sure enough, there are lots of 7 supplies around - for example TRC Electronics addition, most of these will have ±5% adjustment so, for the original application which required 7, I could just have
AC to DC Converter Circuit Diagram
The other type of converter is SMPS or Switch mode power supply which uses high-frequency small transformer and a switching regulator to provide DC output. In this project, we will discuss traditional Transformer based design which use simple diodes and capacitor to convert the Alternating current into Direct Current and an optional voltage regulator to regulate the output DC voltage.
IC Voltage Regulators-with Circuit Diagram - Design & Theory
Given below is the circuit diagram of switching voltage regulator using LM 2575. This IC is known for its high efficiency and will clearly replace all 3-terminal linear voltage regulators. The high efficiency of the IC can be obtained even without a heat sink. LM 2577 switching voltage regulator circuit diagram is
