Patent number: 9787219Abstract: A modulation policy for a modular multi-level convertor, determining a switching state of each submodule by combining the current direction of each bridge arm and the capacitor voltage order of the submodules based on a carrier stacking method. The beneficial effects of the modulation policy are that: each phase only needs a modulation wave and N carriers, given N submodules of each upper bridge arm or lower bridge arm of the modular multi-level convertor; the modular multi-level convertor can output N+1 levels without carrier phase shift; N devoted submodules of each phase are guaranteed at any time; and the submodules' capacitor voltage balancing can be controlled without a closed-loop control policy. The modulation policy facilitates adjustment of the modular multi-level convertor voltage and power class, has unlimited number of levels, has a high precision control algorithm, is easy to realize in engineering and saves software and hardware resources.Type: GrantFiled: February 19, 2014Date of Patent: October 10, 2017Assignee: CHINA UNIVERSITY OF MINING AND TECHNOLOGYInventors: Xiaojie Wu, Zheng Gong, Peng Dai, Gaige Liang, Yiwen Geng, Quanjun Guo, Juan Zhou, En Fang, Xia Zhao, Huaxia Dai, Xiao Zong, Guangsheng Liu

Patent number: 7785404Abstract: An air purifier includes a housing, a high voltage power supply, a first electrode assembly in which a wire-like first electrode is either the only first electrode or, alternatively, is spaced sufficiently far from any other such first electrodes so as to avoid undesirable effects upon each other, and a second electrode assembly in which there are a plurality of blade-like second electrodes. The air purifier can be of the type in which air flows through the housing as a result of electro-kinetic effects. To increase air flow velocity, the voltage between first and second electrodes is relatively high, such as 23-50 kV, and the first and second electrodes are accordingly spaced apart a relatively great distance, such as at least 30 mm.Type: GrantFiled: October 2, 2006Date of Patent: August 31, 2010Assignee: Sylmark Holdings LimitedInventors: Shengwen Leng, Guangsheng Liu
