Shape matters - Bipolar sputtering
Dual magnetron sputtering is a state-of-the art deposition technique in production of compound layers for glass coatings, functional films in electronic display technology or photovoltaic cells. Utilization of a pair of cathodes opened the possibility to industrialize large scale reactive sputtering by limiting the arcing probability.
A New Auto Frequency Tuning Algorithm
One countermeasure to fast plasma impedance variations is auto frequency tuning where on a sub-millisecond timeframe the RF power generator sets its fundamental to a frequency value with better matching. Conventional solutions for auto frequency tuning work with a trial and error algorithm. This white paper shows TRUMPF Hüttinger's new approach in which the RF fundamental is constantly FM-modulated with a selectable modulation frequency.
High Power Impulse Magnetron Sputtering (HIPIMS) is the youngest Physical Vapor Deposition (PVD) technique available to the industry. The experience gathered in the last decade of HIPIMS development allowed to equip the new generation of TRUMPF Huettinger units with unique features which guarantee high reliability and adjustability to different process requirements.
Power Conversion System
Single-Stage three-level inverter
Due to its wide DC voltage range, the modular TRUMPF TruConvert AC3025 inverter allows a single stage grid connection approach for high voltage batteries. In terms of cost and efficiency this is the ideal way to connect batteries to the grid, as the hardware effort is reduced to a minimum. Due to physical dependencies the single stage inverter design is limited to batteries with a voltage range from 650 V to 935 V connected to 380 V or 400 V grids.
DC Coupling: The efficient way
The modular TRUMPF TruConvert product family combined with Ampt string optimizers offers a cost-effective, energy-efficient, flexible solution for DC-coupled solar energy storage systems. The modular design allows a flexible scalability for both battery and PV power without the need for additional hardware. This allows an optimized system layout for a wide range of PV coupled storage applications, reducing TCO while increasing energy efficiency at the same time.
