Title
(EN) Compact, configurable power supply for energizing ozone-producing cells
(ZH) 用于为臭氧生产单元提供能量的紧凑的、可配置电源
Abstract
(EN) Improvements in the supply of high-frequency electrical power to ozone-producing cells can be accomplished using the systems and techniques described herein. Application of a DC-DC converter operating at a switching frequency substantially greater than a load frequency, supports generation of a high- voltage AC for powering such cells, while allowing for reductions in component size and reductions in a quality factor of a load tuning circuit. Controllable power inverters used in obtaining one or more of the switching and load frequencies can be controlled using feedback techniques to provide stable, high-quality power to ozone-producing cells under variations in one or more of externally supplied power and load conditions. An inrush protection circuit can also be provided to selectively introduce a current-limiting resistance until an input DC bus has been sufficiently initialized as determined by measurements obtained from the DC bus. The current limiting resistance can be a positive-temperature coefficient thermistor.
(ZH) 高频电功率向臭氧生产单元的供给的改进能够使用文中所述的系统和技术来实现。操作在远大于负载频率的切换频率下的DC到DC转换器的应用支持了用于为此种单元供电的高压AC的生成,同时允许了元件尺寸的减小以及负载调谐电路中质量因子的减小。用于获得一个或多个切换及负载频率的可控功率逆变器可利用反馈技术来控制,以在外部提供的功率及负载条件中的一个或多个发生变化时向臭氧生产单元提供稳定的、高质量功率。浪涌保护电路也可提供以选择性地引入电流限制电阻,直至输入DC总线已被有效初始化,该有效初始化由从DC总线获得的测量值来确定。电流限制电阻可以是正温度系数热敏电阻。
