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 ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

Engineers often face design goals with conflicting requirements. For instance, take a design that requires an input capacitor to stabilize the bias voltage and present clean dc power to the device’s ...

Damage to a relay contact after cyclic current loading. A better understanding of inverter reliability will help boost performance and reduce costs. Image: Fraunhofer IMWS. Inverters are critical to ...

Underlying concepts of switched-capacitor circuits. IoT power management using a resonant switched-capacitor dc-dc converter or ultra-low-power switched-capacitor voltage regulators. For Part 2, go ...

The smart grid uses gathered information and data to help improve efficiency, reliability and distribution of electricity to utility customers. As Georgia Power neared the completion of its advanced ...

Today's engineer is faced with several options when selecting capacitors for use in high reliability switch-mode power supply (SMPS) applications. Each type has advantages and disadvantages that are ...

Back in school when being introduced to the basics of electrical engineering, we learned that the ideal capacitor was a simple, basic reactive element. It was easily modeled with capacitive reactance ...
