Industrial air pollution in Europe costs up to 189 billion annually, of which 4 billion isdirectly attributed to suspended particulate matter (PM), stimulating mandatory air qualitycontrol measures. Electrostatic precipitation (ESP) is an effective method to charge andcapture transient dust particles, using large electric fields produced by high voltage (HV) DCpower supplies, with performance highly dependent on the DC properties. Historically, linefrequency (LF) HVDC supplies have prevailed but the continual reduction in the level oftolerated emissions has placed a ceiling on the effectiveness on these power supplies due toperformance limitations. In contrast high frequency (HF) HVDC supplies based on seriesresonant conversion (SRC) are highly compact and have been shown to significantly increasethe emissions performance of ESP due to improved average power, stability and control of theoutput. However, the complexity of existing HF HVDC supplies is greatly increased, leadingto difficulties with component failure, thermal management and higher installation/throughlifecosts.Castlet Ltd (CL) seek to lift these restrictions by developing a compact, high-performance,low-cost power supply - type-approved for ESP applications – underpinned by a novelmodulation scheme for insulated gate bipolar transistors (IGBT). Building on a technicalfeasibility study and KTP activities - and using CL’s expertise in power electronics - theproject aims to provide a step-change in output voltage limit, dynamic range, power factor,thermal load and scalability, driving uptake and improvement in air quality control withrespect to existing ESP power supply technologies. Project outcomes will be demonstratedthrough prototype power supplies installed for field testing in the energy, cement and steelindustries.

欧洲工业空气污染每年造成的损失高达1890亿欧元，其中40亿欧元直接归因于悬浮颗粒物（PM），这刺激了强制性的空气质量控制措施。静电除尘（ESP）是一种利用高压直流电源产生的大电场对瞬态粉尘进行荷电和捕集的有效方法，其性能高度依赖于直流电源的特性。从历史上看，线路故障（LF）高压直流电源已经占了上风，但由于性能限制，容许排放水平的不断降低已经对这些电源的有效性设置了上限。相比之下，基于串联谐振转换（SRC）的高频（HF）HVDC电源非常紧凑，并且由于改善了平均功率、稳定性和输出控制，已被证明可以显着提高ESP的排放性能。然而，现有的高频高压直流电源的复杂性大大增加，导致元件故障、热管理和更高的安装/通过寿命成本的困难。Castlet有限公司（CL）试图通过开发一种紧凑、高性能、低成本的电源来解除这些限制，该电源通过了ESP应用的类型认证，并以绝缘栅双极晶体管（IGBT）的新型调制方案为基础。在技术可行性研究和KTP活动的基础上，并利用CL在电力电子方面的专业知识，该项目旨在提供输出电压限制、动态范围、功率因数、热负载和可扩展性方面的阶跃变化，推动现有ESP电源技术在空气质量控制方面的应用和改进。项目成果将通过安装用于能源、水泥和钢铁行业现场测试的原型电源来展示。
