Soy nuevo en la simulación de LTSpice. He preparado el esquema del siguiente diseño de convertidor Buck DC a DC en la carpeta, es decir C: \ Archivos de programa \ LTC \ LTspiceIV \ Rough \. Mi objetivo es hacer un cargador para un teléfono inteligente que tenga una entrada de 110Vcc y una salida de {5Vdc, 2A}.
No sé qué comandos se deben insertar en el esquema usando simular- > Editar simulación cmd opción para ver los resultados. Quiero verificar el voltaje de salida en el nodo Vout y el valor de Iout usando el probador. También quiero ver las formas de onda pero no sé cómo hacerlo. Entonces, ¿qué cambios debo hacer en el esquema?
Editar: mirando un tutorial LTSpice Buck Converter en youtube, agregado simular- > Editar simulación cmd- > Transitorio- > Tiempo de detención = 100useg. Cuando hago clic en la opción EJECUTAR, no muestra ningún error pero no hay una ventana de forma de onda. En la parte inferior de la ventana del esquema, solo se muestra la fuente del paso al 100% y las iteraciones cambian continuamente.
