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 ...

High-current, point-of-load (POL) buck converters leverage metal-oxide semiconductor field-effect transistors (MOSFETs) to provide the pulse-width-modulation (PWM) pulse train to the output filter.

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 ...

Vishay Intertechnology, Inc. has extended its 193 PUR-SI series of miniature snap-in power aluminium electrolytic capacitors with new voltage ratings of 550V and 600V. The Vishay BCcomponents devices ...

Understanding power factor (PF) is important because it gives us a clear understanding of the efficiency of an electrical system. Put simply, it’s the ratio of true power and apparent power, which ...

Switching has almost always meant “hard" switching, which is simple but comes with all kinds of electrical and thermal stresses. Soft switching employs more sophisticated ...

High-voltage DC systems are tricky and take up space. Now, a capacitor can reduce parts, save board space, and make designs ...

In power electronics, design engineers strive to deliver more power in a more efficient manner, and in smaller footprints at all stages of the power-delivery chain, from the smart grid to the end ...

An undervoltage or voltage sag is a disturbance that commonly occurs during electrical faults or when equipment is turning on. They are produced when large currents are being drawn on the system. On ...
