Abstract

Rectificador con factor de potencia próximo la unidad, que comprende un puente de semiconductores (T1) y (T2) que son tipo IGBT (Insulate gate bipolar transistor), con elevadas frecuencias de conmutación, cuyo disparo se efectúa modulando en cada rama o fase los tiempos de conducción en anchura de impulsos, en función de la tensión presente en la salida y en la entrada, de tal forma que estando en fase la tensión y la corriente en cada fase, permiten lograr un coseno de fi unitario, que conjuntamente con una mínima distorsión, armónica facilita la consecución de un factor de potencia próximo a la unidad.
