PSU Burner – a power supply tester

Intro What does one do when designing a power supply? Well, build a power supply tester, of course. One of the simplest things to build is a constant current load. This will allow for testing of the endurance of the power supply, as most of the designs out there are using slow components. However, I wanted to make a better one: one that I could hook up to my Analog Discovery and generate a test waveform to ...

Reference design; USB Type-C PD charger delivers 18W

This joint reference design describes an 18W, USB PD compliant, AC-DC power converter. The design, titled DER-567, pairs the WT6630P USB Type-C PD controller from Weltrend with Power Integrations’ InnoSwitch-CP off-line CV/CC flyback switcher IC, to produce a compact and highly energy-efficient standards-compliant power adapter, that PI says will deliver faster charge times for the larger batteries required ...

Do you know, what´s a top-class programmable power supply capable of?

If you need to simulate overvoltage, slow start, fluctuations and other situations, which may occur in real life, then the TDK Lambda power supplies won´t disappoint you. Imagine a laboratory (testing) power supply able to provide a virtually any function. Switching on, drop-out, repeated switch-on and many other functions, by which we can test our product in a „single shot“ - those are programmable laborat ...

A new multi-function power supply unit for my Embedded Lab

One important parameter in embedded system designing is power consumption. This parameter is directly related to the battery lifetime, if the system is to be powered from a battery. In order to determine the power rating of your designed system, you need to know how much current the system draws from the source at a given voltage. While working on my projects, I usually measure current by placing an externa ...

AmpStrike – Battery Powered Bench Power Supply

Linear Voltage Regulator The power supply runs on a linear voltage regulator built on discrete components. The design of the linear regulator was inspired by the user Amspire from the EEVblog forum. The basic idea is that the Q1 pass transistor and U5A op amp act in a classic voltage regulating loop. U5A gets feedback from the output voltage and acts on Q1 in such a way that the output voltage equals the re ...

50,000V High Voltage Power Supply

DISCLAIMER: This is an extremely dangerous project, and it should only be attempted by people with experience in electronics, and specifically, High Voltage. If it's your first time seek help for your own safety. Homemade High Voltage supplies are unlikely to meet any international standards, the safety and correct operation is NOT guaranteed at all, and will depend on the skill level of the builder, the ef ...

TTPSU – Power supply for turntables with AC motors

The power supply descriped here, is for turntables with 2 phase AC motor, like Linn, Rega, AR, Heybrook, Goldring and many, many more. The main features of the power supply are: X-tal controlled speed. The TTPSU can change speed by the push of a button - no need to move the belt on the pulley. Speed selection - 2 to 4 speeds can be configured and adjusted. Speed adjustment by varying the AC frequency in 0.1 ...

Miniatur Power Supply Unit with 0..24V and 0..3A

Very small power supply unit in the size of a cigarette box. The input voltage is 24V. Its supplied by a external switch mode AC/DC PSU. The output voltage range is 0V to 24V at 0A to 3A. A switch mode preregulator reduces the power loss. This allows a very compact design. Voltage and current are displayed on a RGB OLED display.   Parts List: Miniatur Power Supply Unit with 0..24V and 0..3A ...
