Abstract

UNA CARGA ELECTRONICA DE ALTA FRECUENCIA PARA UNA LAMPARA DE DESCARGA (20) INCLUYE UN FILTRO (S) LC Y UN CIRCUITO (8) DOBLADOR DE TENSION QUE ACOPLA TERMINALES (1, 2) DE ENTRADA DE CA A TERMINALES (13, 14) DE ENTRADA DE CC DE UN CIRCUITO (15) CONVERSOR CC/CA DE SEMI-PUENTE. UN EXTREMO DE LA LAMPARA ESTA ACOPLADO A LOS CONDENSADORES (16, 17) DEL CIRCUITO DOBLADOR DE TENSION A TRAVES DE UN CONDENSADOR (21) DE ACOPLAMIENTO Y LOS DIODOS (11, 12) DEL DOBLADOR DE TENSION, AL OTRO EXTREMO DE LA LAMPARA SE ACOPLA A TRAVES DE UN CIRCUITO (24, 25 Y 26) LC A UN PUNTO DE UNION (22) ENTRE PRIMER Y SEGUNDO TRANSISTORES (18, 19) DE CONMUTACION DEL CIRCUITO DE SEMI-PUENTE. UN CONDENSADOR (31) EN PARALELO CON LA LAMPARA FORMA PARTE DE UN CIRCUITO RESONANTE QUE INCLUYE LA LAMPARA Y EL CIRCUITO LC DE MODO QUE EL CIRCUITO DE SEMI-PUENTE OSCILARA A UNA ELEVADA FRECUENCIA. ENERGIA ES RETRO ALIMENTADA A LOS CONDENSADORES DEL DOBLADOR DE TENSION A TRAVES DEL CONDENSADOR DE ACOPLAMIENTO Y EL CIRCUITO LC PARA MANTENER LA TENSION DEL CONDENSADOR SOBRE EL PICO DE LA TENSION DE SUMINISTRO DE CA Y POR ELLO PROPORCIONA UN CIRCUITO CON ALTO FACTOR DE POTENCIA Y CORRIENTE DE LINEA CON REDUCIDOS ARMONICOS.
