Source: tektonministries.org . LEDs are increasingly being used as energy saving light sources as a response to new energy regulations. They have decisive advantages over conventional lights: they consume less energy, have longer lifetimes, and are ...

In a synchronous, buck switching power supply, the two FETs and the output inductor meet at the phase node (Figure 1). The phase node often connects directly to the control IC. The voltage on this node swings from the input voltage to some voltage ...

Last October, after seven months of silence due to a major upgrade of the 70 m wide radio antenna located in Canberra, NASA sent a set of commands to a 43 year-old spacecraft, Voyager 2. Billions of miles from earth since its launch in 1977, ...

Galvanically isolated power supplies are used in numerous applications for different reasons. In some circuits, galvanic isolation is necessary due to safety considerations. In other circuits, functional isolation is used to block any interference ...

EDN As much as we’d prefer to be able to use just unforced, natural convection cooling, many designs and installations simply cannot be cooled adequately by the low level and uncertainty of airflow that this low-cost, reliable approach ...

By Michael O'Loughlin EDN In certain applications, design requirements may call upon a system's switched-mode power supply to more promptly deliver its output than would the garden-variety power supply. Figure 1 shows such a supply's ...

Question: How do you measure inductor current? Answer: Switched-mode power supplies commonly use inductors for temporarily storing energy. In the evaluation of these power supplies, it is often useful to measure the inductor current to gain a ...
