Why a power-factor correction device is better suited to industrial applicationsMohit Arora
A switching circuit of some kind will be required, and one of the most common types of circuits that can implement this improvement is called a "boost power factor correction" (or "boost PFC") circuit. As the name suggests, this circuit is based on a boost conver...
Or is DCM in reference to something other than the output to the LED? Still, if so, why is DCM desirable in any LED driver? UPDATE: Why DCM is used in the power stage was answered in the comments. I still wonder if DCM is ever desirable in the output to the L...
The last core analog component of the VRM that we will be exploring is theCapacitor. It is a common electrical component used in many electronic devices to store energy in an electric field, and when required, it can discharge this energy into the circuit they are connected to. It acts lik...
If the power factor is capacitive then penalization starts whencos(ϕ)<0.95cos(ϕ)<0.95, and the penalization factor isρ=0.95−cos(ϕ)ρ=0.95−cos(ϕ)(rare) On my client electricity tariff segment (AT-4.3), the penalty fee due low power...
ground balls, is it parallel to the plate for hitting line drives with power or is it upward for long fly balls. Gifted hitters can change swing planes depending on game situations. Most hitters need consistency and coach supervision, critiquing, and correction to create and consistently be on...
power flows and ensure orderly operation of the grid. Then, when load is down (generally in the early morning hours), the frequency can be adjusted to “zero out” the accumulated time offset. System time and frequency monitors provide the information required to do this, by measuring and ...

First, a click position is selected based on the direction of the scrolling action and the typical requirements of scrolling actions in the current task context. This click position is then further adapted to the absolute extent of the required scrolling action. If that was the case, the ...
Users are required to rate their confidence in each flashcard. After each answer is revealed, the user must rate how well she had known the answer, on a scale of 1-5 (where 1 means that she had been clueless, and 5 means that she'd known it perfectly). See Figure 7. Not only doe...
