A variable dc power supply is one of the most useful tools on the electronics hobbyist’s workbench. This circuit is not an absolute novelty, but it is simple, reliable, “rugged” and short-proof, ...

The circuit diagram and working of Variable Voltage Power Supply from Fixed Voltage Regulator is explained in detailed manner. The voltage regulator is used to offer fixed voltage at the output ...

Every automated system that tests electronic circuit boards, modules, or equipment needs one or more DC power supplies. DC supplies provide power to the device under test as well as test stimulus. For ...

When you set out to build a 60,000-volt power supply and find out that it “only” delivers a measly 50,000 volts, you naturally have to dive in and see where things can be improved. And boy, did ...
