Power efficiency formula η = Pout / Pin For example, the efficiency of a converter that provides 500W of output power (Pout) and requires 625W for the input power (Pin), would be 80% (500W/625W=0.80).

A negative-input buck-boost converter IC operating in continuous conduction mode produces a positive output voltage using an external power MOSFET and PNP transistor.

To maintain dc-dc converter stability, power-system designers typically operate under the assumption that input-source impedance should be small compared to the converter's input impedance. But ...

The formula shows that the efficiency gain of bifacial solar cells increases with light reflected from a surface. Significantly more power would be converted from light reflected off of concrete, for ...
