A blast from the Elektor archives: this 1998 battery tester uses a simple LED display to reveal a battery’s true condition ...

Performance under transient loads has become the most important specification of voltage regulators used to power a wide array of products whose current demands vary quickly during operation. Testing ...

Is the battery empty, or is there something wrong with the device? That’s always a difficult question when your walkman or some other battery-powered device appears to be dead when you switch it on.

Using the fast dynamic load described in this Design Idea to test the transient response of a power system can reveal many critical operating characteristics. The voltage deviation resulting from a ...
