Variable regulated power supplies are handy tools found on well-equipped electronics lab benches. The symmetrical varieties that produce equal voltage outputs of opposite polarity, are even more so.

What is duty cycle? Duty cycle is defined by the percentage of high voltage duration in a complete digital pulse. If the duty cycle is 50%, then it will remain on for exact half the duration of the ...

When you have completed this tutorial, you should be able to achieve the following objectives: Given a desired system reliability percentage, correctly identify the power solution required to achieve ...

Texas Instruments Incorporated introduced two high-efficiency PWM power supply controllers with integrated, programmable-delay synchronous rectifier control outputs and pre-bias start-up circuitry.

How switch-mode power supplies changed the power-supply design space. The isolation factor in power supplies: galvanic isolation vs. non-isolated. Most common non-isolated topologies. This series ...
