1-03-2002 | Some designs, because of lack of space or for some other reason, do not use a power supply transformer. Instead, an ‘AC voltage dropper’ in...

1-01-2002 | The digital benchtop power supply is controlled by a microcontroller programmed in PIC BASIC, while a Visual BASIC program is responsible fo...

1-12-2001 | The construction of the Digital PSU requires extra care and precision. Just like the electronics inside, the mechanical construction and ove...

1-12-2001 | This circuit shows one way to generate both positive and negative output voltages using a step-down switching regulator. The Micrel (www.mic...

1-11-2001 | Every electronics laboratory needs a powerful regulated bench supply. In the model described here a microcontroller monitors the actual and...

1-11-2001 | In designing a product that is powered from the mains, there are various factors that ultimately determine the choice of power supply. Incre...

1-07-2000 | This power supply has been specially designed for the 20th-order filter described elsewhere in this issue, but it can also be used for a leg...

1-07-1999 | In certain direct-current operated circuits, such as DC-to-DC converters, the switch-on current may be so high that the output voltage of...

1-07-1999 | There are applications in which it is important for the supply voltage to be largely independent of the level of the output current, which...
