Power supplies that use diodes to rectify an ac voltage to obtain a dc voltage must deal with inherent inefficiencies. A standard diode or ultra-fast diode can have a 1-V forward voltage or higher at ...
comprise a transformer, rectifier, and filter capacitor. Many single-voltage power suppliesconsist of a transformer, arectifier, and a filter capacitor, as shownin Figure 1. This circuit is ...
You can combine a carefully chosenop amp, a low-thresholdP-channel MOSFET, and two feedbackresistors to make a rectifier circuit withless forward drop than a diode (Figure1). The rectified output ...
EL SEGUNDO, Calif. - International Rectifier (NYSE: IRF) today introduced iPOWIR™ technology, a whole new way to design on-board DC-DC converters for computing and communications equipment. EL SEGUNDO ...
And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...
