A convex function is a real-valued function defined on an interval with the property that its epigraph (the set of points on or above the graph of the function) is a convex set.
A rectifier is a electrical device that converts alternating current to direct current, a process known as rectification. Rectifiers are used as components of power supplies and as detectors of radio signals. Rectifiers may be made of solid state diodes, vacuum tube diodes, mercury arc valves, and other technologies.
Report Abuse. An inverter is used to convert DC power to AC. It can control the speed of an AC motor through varying the drive frequency. The AC power is converted to DC by means of a rectifier and re-converted on the inverter side back to AC.nverter is used to convert DC to AC form... just the opposite of rectifier which converts AC to DC... actually it's not solely related to motors but it is a part of an electrical system whenever it is needed..
