Ceramic capacitors are small, they don’t leak, they’re convenient, but they are downright strange. Certain types of caps will lose their capacitance depending on the voltage they’re operating at. If ...

Capacitor Voltage Transformers (CVTs) are central to modern power systems, where they not only scale high transmission voltages into measurable signals but also ensure the precision needed for ...

A few years ago, after more than 25 years of working with these things, I learned something new about ceramic capacitors. I was working on an LED light-bulb driver and the time constant of an RC ...

The inverters and charging systems in hybrid or fully electric vehicles provide a topical example of a high-voltage application that faces extreme space constraints. When multilayer ceramic capacitors ...

Dialog Semiconductor has announced a 10A switched-capacitor voltage divide-by-two, that operates at up to 98% efficiency, hitting or exceeding 95% at 10A. Called DA9313, it can deliver over 50W from ...

Tantalum surface-mount capacitors have gained widespread favor for bulk decoupling use in both conventional and switch-mode power supplies (SMPSs) since their introduction more than 20 years ago.

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...

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 ...

As the cost to produce supercapacitors (SCAPs, or ultracapacitors) continues to decline, they are carving out a niche in the marketplace between conventional capacitors and batteries. And, although ...
