Coaxial Power Systems Limited (CPS) has identified the need for an overhaul of industrial RF generator technology, addressing inefficient legacy generator designs, improving the weld quality and efficiency of RF welding plant, removing obsolescent electronic valve amplifier technology, and enabling manufacturers to automatically stabilise the weld power and to weld faster.The HiSpRing RF generator project represents a low-cost, high-reliability embodiment of the power monitoring & matching technology commonly used in scientific and medical applications, coupled with a solid-state amplifier architecture now common-place in radar and data-communications applications, suitably ruggedized for industrial welding environments. The key innovation is the demonstration of a kilo-Watt RF Generator with self-tuning (in an RF welder application) achieved in sub-millisecond timescales. With the HiSpRing RF generator, efficiency of the welding system is improved, enabling lower running (energy) costs, improved reliability, and reduced maintenance down-time. Improved load matching (and consequent reduction in RF power required for welding) reduces the RF power level needed in the welding equipment, and improves the quality of the welded material.Given the dated state of installed industrial RF Welder Generators world-wide, the performance, reliability, power consumption and size & weight efficiencies offered by this HiSpRing RF generator are game-changing, and disruptive to a largely US- and Far East-based incumbent competitor base. Support for the HiSpRing project has been obtained from multi-national medical packaging and performance footwear manufacturers, who already recognise the process and cost benefits in their RF welding manufacturing processes, offering superior weld characteristics to thermal welding, combined with fine control and improved quality assurance throughout the weld.The culmination of the project will be demonstration of the new RF generator in an RF welding workstation, to support dissemination of system-level characteristics and performance, alongside the performance characteristics of the new HiSpRing RF generator module. HiSpRing also addresses the wider challenge of improving manufacturing productivity (a persistent problem in the UK).

Coaxial Power Systems Limited（CPS）已确定需要对工业射频发生器技术进行彻底改革，解决低效的传统发生器设计，提高射频焊接设备的焊接质量和效率，消除过时的电子阀放大器技术，并使制造商能够自动稳定焊接功率并加快焊接速度。HiSpRing射频发生器项目代表了一种低成本，这是科学和医疗应用中常用的功率监控和匹配技术的高可靠性实施例，与现在雷达和数据通信应用中常见的固态放大器架构相结合，适合于工业焊接环境。关键的创新是展示了一个千瓦的射频发生器，具有在亚毫秒时间尺度内实现的自调谐（在射频焊机应用中）。使用HiSpRing射频发生器，焊接系统的效率得以提高，从而降低运行（能源）成本，提高可靠性，并减少维护停机时间。改进的负载匹配（从而减少焊接所需的射频功率）降低了焊接设备所需的射频功率水平，并提高了焊接材料的质量。考虑到世界范围内已安装的工业射频焊机发生器的过时状态，这款HiSpRing射频发生器提供的性能，可靠性，功耗和尺寸和重量效率是改变游戏规则的，并对主要位于美国和远东的现有竞争对手基地造成破坏。HiSpRing项目得到了多国医疗包装和高性能鞋类制造商的支持，他们已经认识到射频焊接制造工艺的工艺和成本效益，提供了热焊接的上级焊接特性，结合整个焊接过程的精细控制和改进的质量保证。该项目的高潮将是在射频焊接工作站中演示新型射频发生器，支持系统级特性和性能以及新型HiSpRing射频发生器模块的性能特性的传播。HiSpRing还解决了提高制造业生产力的更广泛挑战（这是英国的一个长期问题）。
