Abstract
UNA FUENTE DE CORRIENTE ACCIONADA POR UN DIODO CUASISONANTE PROPORCIONA CORRIENTE DE IMPULSOS DE ALTA POTENCIA QUE ACCIONAN DIODOS EMISORES DE LUZ Y SIMILARES. LA CORRIENTE DE SALIDA DE IMPULSOS DE LA FUENTE DE CORRIENTE ACCIONADA POR DIODOS CUASI-RESONANTES, ES PERCIBIDA Y REGULADA AL NIVEL REQUERIDO POR LOS DIODOS EMISORES DE LUZ POR UN BUCLE DE CONTROL. EN UNA MODALIDAD ESPECIFICA DEL INVENTO, SE DESCRIBE UN TRANSFORMADOR DE FASE OPUESTA CUASI-RESONANTE DE ONDA COMPLETA CONMUTADO POR CORRIENTE CERO, QUE PROPORCIONA UNA CORRIENTE DE SALIDA DE IMPULSOS DE ALTA AMPLITUD REQUERIDA PARA ACTIVAR UNOS DIODOS DE BOMBARDEO EMISORES DE LUZ EMPLEADOS EN LASER DE DIODOS DE BOMBARDEO EN ESTADO SOLIDO. EL EMPLEO DE UN TRANSFORMADOR CUASI-RESONANTE COMO FUENTE DE IMPULSOS PROPORCIONA UNA TRANSFORMACION DE MUCHA MAYOR EFICIENCIA QUE LAS FUENTES DE CORRIENTE LASER CONVENCIONALES. ESTA MAYOR EFICIENCIA TIENE COMO RESULTADO UNA MENOR EXTRACCION DE CORRIENTE DE ENTRADA DE LA FUENTE DE ENERGIA Y UNA ACCION REFRIGERADORA, PRODUCIENDO UNA FUENTE DE CORRIENTE DE MAYOR FIABILIDAD.
