Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor to aid in its starting or a run capacitor to improve its running ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

So you have power circuit breakers at your facility, and they seem to be just fine, sitting there quietly doing their job. What you may not realize is that even though your circuit breakers are ...

In-circuit test (ICT) has been instrumental in identifying manufacturing process defects and component defects on countless varieties of populated printed circuit board (PCB) assemblies for more than ...

Capacitors behave differently than resistors, where resistors allow a flow of electrons through them directly proportional to the voltage drop, and capacitors oppose changes in voltage by drawing or ...

Designers have long used the gyrator circuit to create a virtual inductor employing readily available capacitors. The circuit can achieve high inductance values with relatively low capacitance values, ...

There are many applications which require pulse power. The needed burst of energy is derived by rapidly discharging a previously charged capacitor. As the energy stored in a capacitor is equal to ...
