Abstract

UNA TENSION DE ALIMENTACION PRINCIPAL DE CORRIENTE ALTERNA RECTIFICADA DE ONDA COMPLETA (V1) SE PRODUCE DESDE UN VOLTAJE DE ALIMENTACION DE LA RED DE SUMINISTRO DE CORRIENTE ALTERNA (VM) SIN NINGUN FILTRADO DE PASO BAJO. LA TENSION RECTIFICADA SE DESARROLLA EN UNA BOBINA (W1) DE UN TRANSFORMADOR DE BARRIDO HORIZONTAL (T). LA BOBINA DEL TRANSFORMADOR DE BARRIDO HORIZONTAL TAMBIEN SE ACOPLA A UN TRANSISTOR DE CONMUTACION (Q1) QUE GENERA EN LA BOBINA UNA PRIMERA PLURALIDAD DE IMPULSOS DE CORRIENTE (IP) A UNA FRECUENCIA (20 KHZ50KHZ) QUE ES MAYOR QUE LA FRECUENCIA DEL VOLTAJE DE ALIMENTACION DE LA RED DE SUMINISTRO (50HZ). LOS IMPULSOS DE CORRIENTE DAN ENERGIA A UN CIRCUITO DE CARGA (LOAD). UN VOLTAJE ELECTROSTATICO (V4) SE ACOPLA POR MEDIO DE UN SEGUNDO TRANSISTOR DE CONMUTACION (Q2) A LA BOBINA PARA PRODUCIR EN LA BOBINA UNA SEGUNDA PLURALIDAD DE IMPULSOS DE CORRIENTE (IP2) QUE DAN ENERGIA AL CIRCUITO DE CARGA DURANTE UNA PARTE DEL PERIODO DEL VOLTAJE DE SUMINISTRO DE LA RED QUE NO SE PRODUCEEN LA PROXIMIDAD DEL PICO DEL VOLTAJE DE ALIMENTACION DE LA RED DE SUMINISTRO. CUANDO SE GENERA LA SEGUNDA PLURALIDAD DE IMPULSOS DE CORRIENTE, EL VOLTAJE DE ALIMENTACION DE LA RED DE SUMINISTRO SE DESACOPLA DE LA PRIMERA BOBINA.
