3 Descripciones de Half-Brick MI-270N Serie Mil-COTS DC DC Converter

Los convertidores DC / DC de la serie MI-270N Half Brick utilizan topología de circuito de dos etapas, la primera etapa es la etapa de regulación de voltaje, la segunda etapa es la etapa de aislamiento de entrada y salida. El voltaje de salida produce una señal de amplificación de error por un amplificador de error. Esta señal se usa para controlar la relación de trabajo de la forma de onda PWM, controlando así la tensión de salida de todo el módulo.
Estos productos de la serie tienen una estructura de circuitos modulares con tecnología montada en superficie de PCB, dentro de los productos, utilizando material de conductividad para incrustación y placa base de aluminio para enfriamiento. Los contornos de los productos son compatibles con productos similares de SynQor, y sus pasadores pueden ser reemplazados.
