【摘要】：高频高压变压器在电容器充电电源、脉冲强磁场系统、静电除尘等诸多领域有重要应用,为了提高变压器运行的可靠性,该文以减小高频高压变压器的分布电容和限制其损耗作为设计时的优化目标,并针对此目标提出了一种基于Lagrange数乘法的高频高压变压器分布电容的优化设计方法。并依据此设计方法绕制了一台输入电压500V,输出电压10kV,额定频率15kH z,额定功率为30k V×A的高频高压变压器。对所设计的变压器进行了仿真和实验,得到的分布电容和损耗与理论计算结果一致,且满足绝缘和损耗要求,验证了文中建立的Lagrange模型的准确性。将优化后的变压器与未优化的变压器进行充电对比实验,优化后的变压器充电速度更快,线性度更好,实验结果验证了该优化设计方法的有效性和可行性。
[Abstract]:High frequency and high voltage transformers have important applications in many fields such as capacitor charging power supply, pulse strong magnetic field system, electrostatic precipitator and many other fields. In order to improve the reliability of transformer operation, this paper aims to reduce the distributed capacitance of high frequency and high voltage transformer and limit its loss as an optimization target in design, and a kind of Lagrange based on this target is proposed. The optimal design method of a multiplicative high frequency and high voltage transformer distributed capacitance is made. Based on this design method, a high frequency and high voltage transformer with input voltage 500V, output voltage 10kV, rated frequency 15kH Z and rated power of 30K V x A is made. The designed transformer is simulated and tested, and the distribution capacitance and loss and theoretical calculation are obtained. The results are consistent and meet the requirements of insulation and loss. The accuracy of the Lagrange model established in this paper is verified. The optimized transformer is compared with the unoptimized transformer. The optimized transformer has a faster charging speed and better linearity. The experimental results verify the effectiveness and feasibility of the optimized design method.
