A capacitor that you charge through a resistor operates at 50% efficiency; hence, many engineers avoid using switched-capacitor dc/dc converters. That efficiency figure holds true only for capacitors ...

Scientists in India have developed a 500 W seven-level inverter prototype based on switched capacitors. The device is reportedly able to achieve a high efficiency despite switching, conduction, and ...

Any physical system design needs both analog and digital functionality. Achieving a modular, programmable design is crucial for the demanding applications of future, which has led to more and more ...

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 ...

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 ...

Nexperia has introduced an inductor-less energy harvesting IC that is able to cold start with 12μW from 270mV. Called NEH7100BU, it can mediate between a harvesting power source, a USB charger, a ...

Halo Microelectronics has introduced a switched capacitor charger dc-dc converter for single Li-ion or Li-po cells that can deliver up to 7A while drawing 3.5A from the supply. Called HL7139, it is ...
