摘要
为了得到高压静电除尘电源工作于串联谐振断续电流模式下的调压特性及选择一种适宜的控制方式,在分析电路工作原理的基础上,通过数学公式推导出了反映电路输出特性的解析表达式,分析了控制参数对电路调压特性的影响。通过仿真主要研究了调频、调占空比和调输入电压3种控制方式下电路特性的对比,结果表明,采用调节输入电压的控制方式具有较低的谐振电流峰值和有效值,是一种适合于高压静电除尘的控制方式,最后通过样机给出了实验结果。
This paper is mainly to study the voltage regulation characteristics of power supply for high voltage electrostatic precipitators when operating under series resonant discontinuous current mode and choose a suitable control method. Based on the operation principle of the circuit, analytic expression reflecting the output characteristics of the circuit deduced by mathematics is gotten. The influence of control ptrameters to the circuit characteristics is analyzed. This paper also compares the output voltage regulation characteristic of three control modes by adjusting frequency, duty ratio and input voltage with simulation results. The results indicate that when input voltage regulation is adopted, the peak and RMS resonant current are lower and is a suitable control method candidate. Experimental results and waveforms are proposed.
