Name

Efficiency Calc

Included

LabVIEW Custom Instrument, Test Circuit

Compatibility

Multisim 11.x, Multisim 12.x

Description

     Efficiency, defined as a the ratio between the useful output power of a circuit to its total input power, plays a very important role in determing the life of batteries and it is an important metric in evaluating the performance of power circuits such as voltage regulators and buck converters. The efficiency calculator allows the users to calculate their circuit efficiency as well as visualizing the power waveform.
