Properly selected components make it easier to design modern, energy-efficient power supplies. In this article we present an ...

At a power-on cycle, inrush current, if not limited, can peak to tens of even hundreds of amps when capacitive load is present, thereby increasing the probability of failure and decreasing usable ...

Rectifiers and ac-dc power supplies employ large bulk capacitors. During power-up, these capacitors require a large amount of current to charge up, resulting in a large inrush current. This inrush ...

Dc/dc converters have evolved from simple three-terminal regulator circuits into complex electronic subassemblies that are critical in the power distribution systems of many applications. Good ...

Restrikes or re-ignitions occur when the dielectric strength of the open gap, during contact parting, is not great enough to withstand the recovery voltage across the open gap. With a capacitive load, ...

Although shunt capacitors offer several advantages at all voltage levels, those advantages come at a price. Not only must you purchase, install, and maintain capacitor equipment, you must be able to ...

In power distribution systems, sudden load increases can cause significant voltage drops. These short-term dips should ideally have no impact on the subsequent power supply components. In power ...

Inrush currents associated with motor starting and transformer energizing can cause interaction problems with other loads in a facility or on the power system. These inrush currents can cause sags ...

Southern States CapSwitcher is a high-voltage capacitor switching device specifically designed to meet the power quality needs of today's electrical systems. This special purpose SF6 capacitor switch ...

• Electrical power sources supply two types of power to inductive loads: real power in kW and reactive power in VAR. • Power-factor correction circuits can be either an individual style or of the bank ...
