電除塵器電源的發(fā)展方向――高頻化和數(shù)字化

摘要：本文以電除塵電源的發(fā)展方向――高頻化和數(shù)字化為題，從理論和實(shí)踐上說明了IGBT高頻開關(guān)電源能克服傳統(tǒng)SCR相控電源的缺點(diǎn)，能提高除塵效率，采用全數(shù)字控制能同時(shí)解決電除塵器系統(tǒng)控制問題。高頻開關(guān)電源是典型的環(huán)保節(jié)能降耗產(chǎn)品，是新建和改造電除塵器的首選供電設(shè)備。文章還提供了電除塵器用高頻開關(guān)電源的線路和控制方案及設(shè)計(jì)原則。 敘詞：高頻開關(guān)電源；系統(tǒng)控制器；全數(shù)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.
