Computer Control Electrostatic Precipitator High Voltage Dc Power Developed

ESP is the one that apply cement, electricity , metallurgy administration waste gas and environmental protection machinery of the dust of trade extensively, he has very remarkable results to the administration of the waste gas and dust, with the control technology of the computer, test the development at full speed of the technology , communication technology and network technology, efficiency and energy-conservation operate and modernization of management offer the wide development space to ESP.Subject this design computer control ESP spend the high-pressure direct current power mainly. 3525 PWM signal produced , through driving circuit, drives IGBT module work, the main circuit adopts the structure of the whole bridge; Step up high-frequency voltage transformer adopt brilliant material magnetism core non- , is it adopt high-pressure direct current superpose the method to output; The part of the controller adopts many kinds of control methods, the high tension supply outputs the sampling signal and passes the control algorithm, change through DA, sends the control foot of 3525, the change which regulates the pulse width is in order to achieve the goal of regulating and outputting the amplitude of voltage.While the introduction voltage transformer is made , obey the performance with some commonly used magnetic material at present; In main circuit part, also to distribute parameter impact on stability carry on theory analyses; At controller part ,it show about LCD, communication not serial, etc. carry on introduction of; Introduced the simple one to the anti-interference method of the system finally.
