Abstract
UN COMPONENTE ELECTRICO COMBINATORIO QUE FUNCIONA BAJO EL PRINCIPIO DE TRANSFORMADOR AISLADOR, EN PARTICULAR, SE HA MEJORADO DE TAL MANERA QUE PRESENTA UN CICLO DURANTE LA FASE DE ACELERACION QUE NO SOBRECARGA LOS COMPONENTES. PARA MANTENER LA TENSION REGULADORA DEL CIRCUITO REGULADOR (RK) DE ELEMENTO COMBINATORIO CONSTANTE DURANTE LA FASE DE ACELERACION, HAY CONECTADO UN CAPACITOR DIFERENCIADOR (CD) EN UN CASO EN PARALELO RESPECTO AL CIRCUITO DIODICO (D1) Y EN EL OTRO ENTRE LOS TERMINALES CATODICOS DE DOS CIRCUITOS DIODICOS (D1 Y D2). EL MANTENIMIENTO DE UNA TENSION REGULADORA CONSTANTE DA COMO RESULTADO UNA ACELERACION UNIFORMEMENTE LINEAL DE LA TENSION DE SALIDA DEL CIRCUITO COMBINATORIA (U A), REDUCIENDO ASI LA CARGA DE LAS DISTINTOS COMPONENTES ESTRUCTURALES .
