Analog Devices has managed to create a 500W switched-capacitor power chip for fixed ratio power conversion at up to 72V and 99% efficiency. Power density up to 4,000W/in 3 is claimed. The main ...

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 ...

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 ...

Switched Capacitor (SC) DC-DC converters are DC-DC switching regulators that use only capacitors and switches to transfer charges between the input and the output. This architecture is an alternative ...

A group of scientists from India has developed a novel single-source switched-capacitor-based multilevel inverter (SCMLI) topology. The novel SCMLI topology has fewer switches than a conventional ...

Not all UPS designs are the same. As a result of cost savings in the very competitive UPS market, some designs may not have the highest level of component reliability. Capacitors are an integral part ...

High-reliability capacitors specifically designed for use in harsh, high-temperature power conversion applications— including military, aerospace, and energy applications — are always in demand.

Analogue Devices has combined switched capacitor and inductive buck conversion in the same topology to reduce the size of step-down dc-dc converters. Called LTC7821, this is “industry first hybrid ...
