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.

Menno van der Veen is well known for his research publications on tube amplifiers used in audio systems. In this book he describes one of his research projects which focuses on the question of whether full compensation for distortion in tubes and output transformers is possible. In the past, a variety of techniques have been developed. One of them has largely been forgotten: trans-conductance, which means converting current into voltage or voltage into current. Menno van der Veen has breathed new life into this technique with his research project titled “Trans”. This book discusses all aspects of this method and discusses its pitfalls. These pitfalls are addressed one by one. The end result is a set of stringent requirements for Trans amplifiers. Armed with these requirements, Menno then develops new Trans amplifiers, starting with Transie 1 and Transie 2. These DC-coupled, single-ended tube amplifiers have unusually good characteristics and are suitable for hobbyist construction. Next the Trans principle is applied to amplifiers with higher output power. A trial-and-error process ultimately leads to the Vanderveen Trans 30 amplifier, which optimizes the features of Trans. The characteristics of this amplifier are so special and unique that Menno believes he has struck gold. To ensure that variations in tube characteristics cannot interfere with optimal Trans behavior, Menno makes use of simulations and comparison with other amplifier types. This book reads like an adventure story, but it is much more – it is an account of solid research into new ways to achieve optimal audio reproduction.

A Hands-on Guide to Crafting Your Own Power Plant The book you are about to read provides a step-by-step guide for building a renewable energy power plant at home. Our goal was to make the book as practical as possible. The material is intended for immediate application with a small amount of theory. Yet, the theory is important as a foundation that saves time and effort by disabusing the readers of potential misconceptions. Specifically, upon having a firm understanding of photovoltaic physics, you will not be inclined to fruitlessly search for 90% efficient solar panels! We want our readers to be the “doers”. If the book gets covered in grime and some pages become torn while you are building your power plant – this is the best compliment to us. The book covers solar and wind energy. Also, a curious power source based on manure is discussed as well, giving the doers an opportunity to further develop the manure fuel cell. It is important to note that there are many companies offering installation of complete solar solutions. Upon installing the panels, the system is not owned by the customer. Therefore, there is no freedom for experimentation and optimization. Also, none can beat the cost of a DIY solution as well as the ultimate satisfaction. All that is written here is a result of us building a renewable energy solution in Southern California. As the book was completed, the energy began flowing!
