HiSpRing Frequency-Agile RF Generator for high-speed welding

同轴电源系统有限公司（CPS）已经确定需要对工业射频发生器技术进行大修，解决低效的传统发生器设计问题，提高射频焊接工厂的焊接质量和效率，消除过时的电子阀门放大器技术，并使制造商能够自动稳定焊接功率并更快地焊接。hisspring射频发生器项目代表了科学和医疗应用中常用的功率监测和匹配技术的低成本，高可靠性体现，加上现在在雷达和数据通信应用中常见的固态放大器架构，适合工业焊接环境。关键的创新是演示了在亚毫秒时间尺度内实现自调谐的千瓦射频发生器（在射频焊机应用中）。使用hisspring射频发生器，可以提高焊接系统的效率，降低运行（能源）成本，提高可靠性，减少维护停机时间。改进的负载匹配（以及随之而来的焊接所需射频功率的降低）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。鉴于世界范围内已安装的工业射频焊机发生器的过时状态，该hisspring射频发生器提供的性能，可靠性，功耗以及尺寸和重量效率将改变游戏规则，并对主要以美国和远东为基础的现有竞争对手具有破坏性。hisspring项目得到了跨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过程中的工艺和成本效益，为热焊接提供了优越的焊接特性，并结合了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演示新的射频发生器，以支持系统级特性和性能的传播，以及新的hisspring射频发生器模块的性能特征。hisspring还解决了提高制造业生产率这一更广泛的挑战（这是英国的一个长期问题）。

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).
