While passive precharge employs a power resistor to create an RC circuit that charges the capacitor asymptotically, active precharge can employ a switching converter with a buck topology that uses ...

Find a downloadable version of this story in pdf format at the end of the story. For decades, 50 V was the maximum voltage rating available for solid SMD tantalum capacitors. With today's requirements ...

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

All buck converters need capacitors on the input. Actually, in a perfect world, if the supply had zero output impedance and infinite current capacity and the tracks had zero resistance or inductance, ...

A high-efficiency buck-boost DC-DC converter was developed by the research team headed by Prof. CHENG Lin from the School of Microelectronics at the University of Science and Technology of China (USTC ...
