SMPSU With A Relay
Switched mode power supply units (SMPSUs) are widely used but challenging to construct independently, and they can be complex to understand in terms of their design principles. Creating a personal SMPSU typically necessitates considerable expertise, hard-to-source components, and a significant...
12V to +/- 20V DC Converter Circuit
A DC to DC converter circuit is designed to convert a DC voltage to another DC voltage with different levels. This specific converter transforms a +12 V DC input into a symmetrical output of +/-20 V DC. Such circuits are...
Automobile-voltage-regulator
A monolithic 555-type timer serves as the core component of this straightforward automobile voltage regulator. When the timer is inactive, resulting in a low output at pin 3, the power Darlington transistor pair remains off. If the battery voltage drops...
General-purpose-power-supply
The supply 6-66 can be utilized for output voltages ranging from 1 to 35 V. The line transformer must be selected to provide approximately 1.4 times the desired output voltage from the positive side of filter capacitor C1 to ground....
Dual Voltage 12V Power Supply
The following circuit diagram of a dual voltage power supply can be used for miscellaneous applications. It requires a few components to build. The most important components of this circuit are regulators: 1: (AN) 7812 and 2: (AN) 7912. AN7812...
Protectors Circuit on SMPS (power supply) Schematic Diagram
The simplest example of a Switch Mode Power Supply (SMPS) utilizes three transistors (C3807, A1015, and power transistors). A common issue that arises is related to the feedback circuit, which can lead to an output voltage (B+) that exceeds safe...
power supply circuit
The SheevaPlug is known to have a suboptimal power supply, particularly affecting users in the UK operating at 240VAC. Additionally, heavy loads on the USB can cause issues, especially when connecting an external mechanical disk drive. This project aims to...
3A Dc-Dc Converter Needs No Heatsink Circuit
This regulator achieves 90% efficiency with a 12-V input and a 5-V output. It utilizes the LT1158 and LT1431 components from Linear Technology, Inc. High efficiency is accomplished by synchronously switching two power MOSFETs in a step-down switching regulator. The...
Increasing Regulator Current
Although the 78xx series of voltage regulators are available with different current outputs, you can boost the available current output with this circuit. A power transistor is used to supply extra current to the load, maintaining a constant voltage. Currents...
