The abbreviations AC and DC are often used to mean simply alternating and direct, respectively, as when they modify current or voltage. [ 1 ] [ 2 ] The usual waveform of alternating current in most electric power circuits is a sine wave , whose positive half-period corresponds with positive direction of the current and vice versa (the full ...
AC, A.C., A/C, or Ac often refers to: ... Other uses in science and technology. Air conditioning, technologies for altering the temperature and humidity of air;
Initially, a region of California known for a large number of electronics technology firms. sine wave The waveform of the mathematical sine function; a fundamental wave shape, free of harmonics. single-phase electric power An alternating current power system using only two wires, where peak voltages in each wire occur at the same time.
The concept of power dissipation in AC circuit is explained and illustrated with the example. For instance, a power factor of 0.68 means that only 68 percent of the total current supplied (in magnitude) is actually doing work; the remaining current does no work at the load. Power Factor is very important in Power sector substations.
The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage. [ 2 ] [ 3 ] Direct current may be converted from an alternating current supply by use of a rectifier , which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only ...
A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current. Power Converters can include simpler tools such as transformer or more complex like a resonant converter .
This glossary of power electronics is a list of definitions of terms and concepts related to power electronics in general and power electronic capacitors in particular. For more definitions in electric engineering, see Glossary of electrical and electronics engineering .
Although much of the field is concerned with the problems of three-phase AC power – the standard for large-scale power transmission and distribution across the modern world – a significant fraction of the field is concerned with the conversion between AC and DC power and the development of specialized power systems such as those used in ...
