Versatile and efficient semi-conductor power amplifier architecture

Transistor-based power amplifiers used in particle accelerators require high power outputs. Due to the limited power output of a single transistor, the target application requires numerous transistors to be combined. The market also requires amplifier systems with different frequencies and power classes. We have therefore developed the TruAccelerate platform to establish this with a similar system architecture.

Solid-state power amplifier system for particle accelerators with unique hot-swap function that withstands full back radiation

In this white paper, we present a hot-swap technology that enables individual failed power amplifier modules to be replaced during operation under ambitious reflection requirements. Particular attention must be paid to the architecture of the combiner and the controlled isolation of the modules.

Meantime between failures (MTBF) and annual failure rate (AFR) for a large installation of solid state power amplifiers

The availability of particle accelerators is a deciding factor. Due to the complex technology, an accurate availability assessment must include the identification of individual errors and a reliable estimate of the failure rate.

DC power for resistance heating in precise MOCVD processes

Metal Organic Chemical Vapor Phase Deposition (MOCVD) is a highly complex procedure for the growth of crystalline layers. MOCVD is implemented for the manufacture of light emitting diodes (LEDs), lasers, transistors, solar cells and other electronic and opto-electronic components, for example, and is the key technology for future markets with high growth potential. TruHeat DC 3000 is the perfect candidate for these applications.

Single-level three-point inverter

The cost and energy efficiency of AC-coupled battery systems for high voltages depends on the performance electronics required for connecting the battery to the power supply system. This article discusses the requirements and dependencies for a single-level approach which can save costs and increase system efficiency.

High efficiency and innovative GaN generator in the 2.45-GHz-ISM band for high-tech microwave applications

To date, the main obstacle and greatest disadvantage in the industrialization of microwave processes has been the lack of "options". Up to now, only mechanically mobile components such as rotating plates, agitators, etc. were available to influence the homogeneity of the heating process and to facilitate a targeted temperature distribution and a reproducible heating process.
