Solid state lighting solutions are increasing in popularity across a broad variety of illumination, indication, signage and backlighting applications, replacing traditional incandescent and ...

You have a 1 MHz sinusoidal voltage signal driven into a 5uF capacitor. You are measuring both the voltage and the current with an oscilloscope. What is the phase of the current in relation to the ...

One of the most common parts to fail on a single-phase HVAC system is a run capacitor, so much so that we sometimes refer to junior techs as “capacitor changers.” While capacitors may be easy to ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

In the conventional dc-dc converter buck topology (Fig. 1), power from the input voltage source is transferred to the output filter by turning on the pass transistor. When the pass transistor is on, ...
