April 11, 2022, 1:47 a.m. Updated 35 {"title": ["", "Development of prototype low-cost electrostatic precipitator voltage supplies based on efficient resonant conversion to reduce industrial emissions"], "description": ["", "\nIndustrial air pollution in Europe costs up to 189 billion annually, of which 4 billion is\ndirectly attributed to suspended particulate matter (PM), stimulating mandatory air quality\ncontrol measures. Electrostatic precipitation (ESP) is an effective method to charge and\ncapture transient dust particles, using large electric fields produced by high voltage (HV) DC\npower supplies, with performance highly dependent on the DC properties. Historically, line\nfrequency (LF) HVDC supplies have prevailed but the continual reduction in the level of\ntolerated emissions has placed a ceiling on the effectiveness on these power supplies due to\nperformance limitations. In contrast high frequency (HF) HVDC supplies based on series\nresonant conversion (SRC) are highly compact and have been shown to significantly increase\nthe emissions performance of ESP due to improved average power, stability and control of the\noutput. However, the complexity of existing HF HVDC supplies is greatly increased, leading\nto difficulties with component failure, thermal management and higher installation/throughlife\ncosts.\nCastlet Ltd (CL) seek to lift these restrictions by developing a compact, high-performance,\nlow-cost power supply - type-approved for ESP applications \u2013 underpinned by a novel\nmodulation scheme for insulated gate bipolar transistors (IGBT). Building on a technical\nfeasibility study and KTP activities - and using CL\u2019s expertise in power electronics - the\nproject aims to provide a step-change in output voltage limit, dynamic range, power factor,\nthermal load and scalability, driving uptake and improvement in air quality control with\nrespect to existing ESP power supply technologies. Project outcomes will be demonstrated\nthrough prototype power supplies installed for field testing in the energy, cement and steel\nindustries.\n\n"], "extra_text": ["", "\n\n\n\n"], "status": ["", "Closed"]}
