Versatile and efficient semi-conductor power amplifier architecture

Transistor-based power amplifiers for use in particle accelerators require high power levels. The limited power of a single transistor means that the target application requires a combination of various transistors. The market also calls for amplifier systems with different frequencies and power classes. We developed the TruAccelerate platform to cater for these requirements as effectively as possible using a similar system architecture.

Solid-state power amplifier system for particle accelerators featuring a unique hot-swap function capable of withstanding full back-reflection

This white paper introduces hot-swap technology that enables individual failed power amplifier modules to be replaced during operation, while meeting ambitious reflection requirements. Particular attention must be paid to the architecture of the combiner and the certified module insulation.

Meantime Between Failures (MTBF) and Annual Failure Rate (AFR) from a large-scale installation of solid-state power amplifiers

The availability of particle accelerators is a critical factor. The complexity of the technology means that identifying individual faults and deriving a reliable failure estimate requires an accurate availability rating.

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.

Innovative voltage regulation for C&I storage systems that enables a seamless transition between the power connection and stand-alone operation

When a battery storage system is capable of establishing and operating local grids in addition to mains operation, it presents significant advantages to the operator in terms of enhanced resilience, robustness and security. In particular, this includes the seamless continued operation of its systems in the event of a supply network failure.

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.

Highly efficient 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 industrialisation of microwave processes was 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.
