Crowbar circuits have long been the go-to safeguard against overvoltage conditions, prized for their simplicity and ...

Many system applications require that capacitors be connected together, in series and/or parallel combinations, to form a "bank" with a specific voltage and capacitance rating. The most critical ...

When testing your devices, it may become apparent that the device needs protection against an overvoltage condition. Most power supplies offer some form of overvoltage-protect (OVP) circuit. The OVP ...

This Single Cell Super Capacitor Protection IC has been tailored explicitly for charging backup power sources under extreme conditions. Backup power is essential in numerous settings, but lithium-ion ...

Lightning, inductive load switching, or capacitor bank switching may cause transient overvoltage conditions in AC line voltage applications such as white goods and appliances. Metal Oxide Varistors ...

Figure 1 shows a switching regulator that can generate a lower voltage from a high voltage. In this type of circuit, the bypass capacitor (CBYP) is especially important. It has to support the switched ...

Editor's note: This article was first featured in the February 2003 issue of EC&M. It has been updated to reflect newer power quality instruments and updated standards. Today, many facilities have ...

An increasing number of commercial and industrial facilities are using adjustable-speed drives (ASDs) with pulse-width modulation (PWM). The benefits include improved efficiency, energy savings, and ...
