電除塵器電源的發展方向――高頻化和數字化

摘要：本文以電除塵電源的發展方向――高頻化和數字化為題，從理論和實踐上說明了IGBT高頻開關電源能克服傳統SCR相控電源的缺點，能提高除塵效率，采用全數字控制能同時解決電除塵器系統控制問題。高頻開關電源是典型的環保節能降耗產品，是新建和改造電除塵器的首選供電設備。文章還提供了電除塵器用高頻開關電源的線路和控制方案及設計原則。 敘詞：高頻開關電源；系統控制器；全數字控制 Abstract：This paper presents digital and the high frequency evelopment direction of a electrostatic precipitator power supply.Theory and practice validate the IGBT High-frequency Switching Power Supply has overcome the shortcoming of SCR Phase control Power Supply and can enhance the dust removal efficiency. This entire digital control way also can control the Electric precipitator system very good. The all above explained that the High-Hrequency Switching Power Supply is a typical product which is energy economization, environmental protection and reduced material. And the　High-Hrequency Switching Power Supply also is the first choice equipment when the electric precipitator is newly built and reconstructed. This paper has also provided the circuit,the control scheme and the principle of design of High-Frequency Switching Power Supply.
