In this video, the presenter will show you how he repaired his lab bench power supply which got damaged through a battery which was connected the wrong way around. Along the way, he will also show you different reverse...
Nowadays, most portable electronic gadgets are powered by USB adaptors. These adaptors have 5V, 1A to 5V, 2.1A output, which is enough to power low-power circuits of different voltages while testing a prototype. This is done either by using...
Useful for electronics hobbyists, this linear workbench/ desktop power supply converts a high input voltage (12V) from the SMPS of a PC into low output voltage (1.25 to 9 volts). An adjustable three-pin voltage regulator chip LM317T (IC1) is...
This stabalised power supply circuit may be directly connected to 230V AC mains to derive output voltages of 3V to 12V DC for connection to the prototyping board.
There are a number of electronics devices that require clear, pulsed power supply. For instance, power consumption of contemporary high-performance processor devices directly depends on the dynamic load of the processor and can vary over a very wide range...
A good bench power supply is the most vital equipment for electronics engineers and hobbyists. However, bench power supplies used in R&D labs are costly. Output rating is also a major issue. A variable DC supply up to 30V...
Almost all electronic gadgets now come with one or more USB ports. You can use the USB port as an automatic switch to control devices powered by mains. Here we present a USB controlled power switch circuit that can control...
