Aus der Reihe "Stromversorgung ohne Stress" (Band 4) Renaissance der linearen Stromversorgungen Mittlerweile gibt es fast nur noch Schaltnetzteile. Da diese rauschen und stören, sind sie nicht für alle Einsatzzwecke die beste Wahl. Ursache sind durch den Schaltbetrieb erzeugte Hochfrequenzschwingungen, die in die Netzleitung und die Umgebung strahlen. Lineare Netzteile liefern Gleichspannungen von höchster Qualität. Über Brummen und Rauschen braucht man sich wenig Sorgen zu machen. Auch der Aufbau ist im Vergleich zu Schaltnetzteilen unkritisch. Wenn man überhaupt von Nachteilen bei linearen Netzteilen sprechen kann, wäre nur das höhere Gewicht zu nennen. Lineare Stromversorgungen sind auch einfach zu verstehen, können aus Standard-Bauteilen aufgebaut werden, sind leicht zu modifizieren und reparaturfähig und damit nachhaltig. In diesem Buch geht es um den Entwurf und den Bau von linearen Stromversorgungssystemen für kleine und große Leistungen. Aber auch Randthemen wie die lineare Steuerung von Verbrauchern und Kompromissen aus Kombinationen von Schaltnetzteil und linearem Netzteil oder Hilfsschaltungen wie lineare Lasten sind Bestandteil des Buches. Bei dieser Gelegenheit gibt es ausreichend Raum für die Besprechung der Grundlagen, der technischen Details, der Fallstricke und von Tipps und Tricks.

The Peak Atlas ESR70 gold is an enhanced version of the previous Peak Atlas ESR70 Plus. It does everything that the ESR70 Plus did but better. It now measures capacitance up to 10x faster, and over a wider range, thanks to new test algorithms. The capacitance measurement is also much less influenced by parallel resistances or leakage current thanks to our new Triple-Slope measurement system. Using the supplied gold plated probes (removable), the Atlas ESR70 gold can measure ESR down to a resolution of 0.01 ohms, up to 40 ohms. It can even measure ESR for capacitors that are in-circuit. Probes are removable, allowing 2 mm compatible probes to be fitted. Audible alerts are produced for various ESR levels allowing you to perform many tests in succession without having to look at the display. The ESR70 automatically takes capacitive reactance into account, so even low value capacitors (down to 0.3 uF) can have the ESR measured accurately. Kenmerken Uses a single AAA Alkaline cell (included). Alphanumeric LCD with backlight. Automatic analysis-start when you apply the probes. Automatic capacitor discharge using controlled discharge function. ESR (and low DC resistance) measurement (even in-circuit). Capacitive reactance automatically taken into account to ensure accurate ESR. Capacitance measurement (if testing out-of-circuit). Audible alerts for various ESR levels. Extended ESR measurement range up to 40 Ohms. Optional probe alternatives easily fitted. New gold Features Improved LCD with better backlight. 10x faster capacitance measurement for large capacitors. Enhanced user options system. New triple-slope measurement system to vastly reduce the influence of parallel resistance and/or leakage current on capacitance measurements. Much wider capacitance measurement range now 0.3 uF to 90,000 uF (was 1uF to 22,000uF). Specificaties Analyzer type ESR and Capacitance Component types Capacitors (>0.3 uF) ESR range 0.00 Ohms to 40.0 Ohms ESR resolution From 0.01 Ohms In-circuit use ESR only Capacitance range 0.3 uF to 90000 uF Battery type 1.5 V Alkaline AAA Cell (supplied). Life typically 1500 ops Display type Alphanumeric LCD (with backlight) Inbegrepen Peak Atlas ESR70 gold Extra-long and extra-flexible test cables (450 mm of Silicone covered cable) 2 mm gold plated plugs and sockets with removeable gold plated crocodile clips Comprehensive illustrated user guide AAA Alkaline cell Downloads Datasheet (EN) User Guide (EN)

Practical Multitasking Fundamentals Programming embedded systems is difficult because of resource constraints and limited debugging facilities. Why develop your own Real-Time Operating System (RTOS) as well as your application when the proven FreeRTOS software is freely available? Why not start with a validated foundation? Every software developer knows that you must divide a difficult problem into smaller ones to conquer it. Using separate preemptive tasks and FreeRTOS communication mechanisms, a clean separation of functions is achieved within the entire application. This results in safe and maintainable designs. Practicing engineers and students alike can use this book and the ESP32 Arduino environment to wade into FreeRTOS concepts at a comfortable pace. The well-organized text enables you to master each concept before starting the next chapter. Practical breadboard experiments and schematics are included to bring the lessons home. Experience is the best teacher. Each chapter includes exercises to test your knowledge. The coverage of the FreeRTOS Application Programming Interface (API) is complete for the ESP32 Arduino environment. You can apply what you learn to other FreeRTOS environments, including Espressif’s ESP-IDF. The source code is available from GitHub. All of these resources put you in the driver’s seat when it is time to develop your next uber-cool ESP32 project. What you will learn: How preemptive scheduling works within FreeRTOS The Arduino startup “loopTask” Message queues FreeRTOS timers and the IDLE task The semaphore, mutex, and their differences The mailbox and its application Real-time task priorities and its effect Interrupt interaction and use with FreeRTOS Queue sets Notifying tasks with events Event groups Critical sections Task local storage The gatekeeper task
