Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

More often than not a question pops up in our forum about speaker impedance and the result of connecting multiple speakers to a single amplifier. Thus we have prepared this introductory tutorial to ...

To understand a series circuit, visualize it. You can do that by making a drawing. Just draw a box, to start with. This box represents your circuit. Notice there is only one path: the perimeter of the ...

Supercapacitors (SCs) generally operate at low voltages of about 2.7 V. To achieve higher operating voltages, it is necessary to build up a cascade of SC cells connected in series. Due to variations ...

With their low equivalent series resistance (ESR), which allows for good ripple-current handling as well as high surge-voltage ratings and self-healing properties, film capacitors are strong ...

SMPS is the abbreviation of switching mode power supply, a kind of high-frequency power conversion device and a power supply device. Its function is to convert a level of voltage to the voltage or ...

What is a pre-charge circuit and what role does it play? The fundamental elements of a pre-charge circuit. Some basic best practices and where to find more information. A common challenge in systems ...
