<Subject>Elec:Aerogeneradores<English>Pulse Width Modulation<SourceEN>Web:http://www.otherpower.com/glossary.html<Def>(abbrev. PWM) A regulation method based on Duty Cycle. At full power, a pulse-width-modulated circuit provides electricity 100 percent of the time. At half power, thePWM is on half the time and off half the time. The speed of this alternation is generallyvery fast. Used in both solar wind regulators to efficiently provide regulation.
