Este documento se divide en dos partes y comienza con una introducción a los principios de conversión CA/CC en general. Se presentan los circuitos más comunes utilizados para diferentes niveles de potencia. Se tratan principalmente los convertidores de fuente conmutada (SMPS), puesto que son los más utilizados en electrónica. Se hace especial hincapié en el diseño de convertidor de transferencia indirecta en diferentes variantes. No obstante, todas las medidas son igualmente aplicables a otros diseños de convertidor SMPS que funcionen con niveles de potencia altos.En la segunda parte del documento se abordan los métodos y procedimientos de medida más importantes de un convertidor CA/CC. Para cada apartado dedicado a las medidas se abordarán primeramente una serie de nociones básicas, para presentar a continuación el método de medida apropiado. En esta segunda parte, el dispositivo bajo prueba (DUT) se considera como «caja negra», por lo que la estructura es similar. De este modo, los apartados sobre las medidas incluyen los métodos para los test de entrada, para los test de salida y una combinación de ambos, como eficiencia. Naturalmente, algunos test ejecutados en la salida del convertidor son también relevantes para un convertidor CC/CC, p. ej. la validación del rizado de la salida.

No glitter-studded rainbows or unnecessary hoopla. Just affordable test instruments, from basic 100 W bench essentials to performance models up to 800 W. Handy as beginner test equipment but capable of tackling multiple measurements simultaneously. Big thumbs up. Curiously-stroking-chin emoji? Have a look at what a portfolio looks like when it puts your needs at the center.

Unique Rohde & Schwarz 170 GHz power sensors ease use and traceability in the D-bandRohde & Schwarz is launching the new R&S NRP170TWG(N) thermal power sensor for precise power level measurements in the D-band. It is the only RF power sensor on the market that offers full traceability to national metrology institutes (NMI) in the frequency range from 110 GHz to 170 GHz, an important prerequisite for commercializing the frequency band. The R&S NRP170TWG(N) hardware is designed to reduce measurement noise and drift, while remaining very accurate and easy to use. The sensors are fully calibrated plug & play devices that can be easily integrated into any measurement setup with a USB or LAN connection.

La conducción autónoma promete a los usuarios unos niveles excepcionales de movilidad y confort, y también incentiva que fabricantes de equipos originales y Tier 1 consigan la anticipada "visión cero", el objetivo de la UE de eliminar las muertes por accidente de tráfico en 2050. No obstante, su éxito tiene un requisito previo importante: los distintos componentes y funciones del vehículo deben coordinarse
No se necesita ninguna fuente externa adicional, todos los dispositivos se reconocen de forma automática y todos los datos de calibración necesarios se transfieren automáticamente. Para la demostración, sin que estén todavía definidos los estándares para la banda D, se genera una señal 802.11ad de 2 GHz de ancho de banda con 148 GHz, se transmite «over the air» y se analiza.
