What is an adjustable power supply?An adjustable power supply is a device that provides a variable output voltage and current to power electronic circuits and devices. It is an essential tool for electronics enthusiasts and professionals who need to test and troubleshoot different types of electrical and electronic systems.
What is a PD adjustable DC power supply?This project wascreated on 06/01/2025and last updated 3 months ago. The PD Adjustable DC Power Supply is a compact, USB-C-powered device designed to provide adjustable voltage output like a traditional lab bench power supply, but using the USB Power Delivery (PD) 60W as power input.
How to build an adjustable power supply circuit?Before building the adjustable power supply circuit, make sure you have all the necessary components. These include a LM317 voltage regulator, resistors, capacitors, diode, potentiometer, heatsink, and wires. Start by preparing the circuit board. Cut it to the desired size and make sure it is clean and free from any dust or debris.
Can a potentiometer be used as an adjustable power supply?Use a multimeter to check the voltage output and adjust the potentiometer to vary the voltage. Make sure there are no short circuits or loose connections. Once the circuit is built and tested, it is ready to be used as an adjustable power supply. It can provide a regulated voltage output that can be adjusted according to your needs.
How to set current limit on PD power supply?Here are the steps to set the current limit on the PD power supply Short the output positive and negative terminal. Now, the power supply should automatically switch into CC mode. Release the shorted terminal, now the power supply should automatically switch back to CV mode. Increase the voltage until the target voltage output is reached.
What components do you need for a power supply?Here is a list of the key components you will need: Transformer: This is used to convert the high voltage AC from the mains power supply to a lower AC voltage. Rectifier: The rectifier is responsible for converting the AC voltage to DC voltage. This can be done using diodes or a bridge rectifi
