There was a time when taking a low DC voltage — say a single battery — and converting it to a higher voltage was painful. Now, however, cheap and easy-to-use DC to DC converters are readily available.

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 ...

Charge pump circuits represent a pivotal technology in modern power management systems, utilising capacitors switched at high frequencies to convert a low input voltage into a higher, regulated output ...
