Switch Mode Power Supply (SMPS) Topologies (part I)
https://www.electronics-lab.com/switch-mode-power-supply-smps-topologies-part-i/
Microchip’s application note describes the basics of different SMPS topologies: The industry drive toward smaller, lighter and more efficient electronics has led to the development of the Switch Mode Power Supply (SMPS). There are several topologies commonly used to implement SMPS. This application note, which is the first of a two-part series, explains the basics of […]

by SHARANYADAS @ instructables.com: I am playing with electronics since i was a child and made numerous circuits.But still now,i didn’t made any power supply unit for general purpose use.So tired of making PSU for each circuit,I decided to make a stable Bench PSU for general purpose use with some enhanced features.I decided to made the […]
Teardown & Repair of a Stanford Research PS350 5000V, 25W High Voltage Power Supply
https://www.electronics-lab.com/teardown-repair-of-a-stanford-research-ps350-5000v-25w-high-voltage-power-supply/
In this episode Shahriar repairs a Stanford Research Systems Model PS350 5000V-25W High Voltage Power Supply. The unit continuously displays 2.5kV without the output being enabled and produces no output voltage. Verification of power supply voltages reveals the issue is linked to a disconnected 15V voltage regulator IC. After the repair, the output voltage is […]
Hardware Protection – OverVoltage and OverCurrent
https://www.electronics-lab.com/hardware-protection-overvoltage-and-overcurrent/
Maurizio @ dev.emcelettronica.com discuss about the different aspects of protecting power supplies from overvoltage and overcurrent. Power processing is one of the most important aspects on electronic design. The power is unique for a typical system because it gives the system life. Before starting to make the project for a power supply we need to analyze […]

https://www.electronics-lab.com/usb-power-supply-active-load-tester/
Sasa Karanovic has designed and built a DIY USB power Supply active load tester, that is available at GitHub: USB Power supply Active Load Tester or short PAL Tester is unit designed for testing the quality of the power supplies. Idea was to create low-cost, precise device for simultaneous measurement of Voltage and Current drawn […]
50,000V High Voltage Power Supply
https://www.electronics-lab.com/50000v-high-voltage-power-supply/
by Victor8o5 @ instructables.com: This high voltage power supply has been designed to output a fixed voltage of around 50kV, it could easily be converted to an adjustable supply by connecting a variac in case of using transformers or by adding some extra circuitry to regulate the power going in. I initially thought about a high […]
Do you know, what´s a top-class programmable power supply capable of?
https://www.electronics-lab.com/do-you-know-whats-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 […]
