基于拉格朗日数乘法的高频高压变压器分布电容优化设计
Optimal Design Based on Lagrange Multiplier Approach for Parasitic Capacitance of High Frequency High Voltage Transformers
摘要
Abstract
High frequency high voltage (HFHV) transformers are widely used in applications such as capacitor charging power systems (CCPS), pulsed high magnetic field systems and electrostatic dust collectors etc. In order to minimize the value of the parasitic capacitance as well as the total power loss of the transformer, an innovative optimum design method of HFHV transformers based on Lagrange multiplier approach was presented. A 15 kHz, 30kV?A transformer prototype was designed with 500V input voltage and 10kV output voltage. The simulation and experiment were given to prove the performance of the transformer prototype. The value of capacitance and loss which meet the loss constraints and insulation requirements are the same to theoretic calculation results. The results verify the accuracy of the Lagrange model established in the paper. In addition, compared with the traditional transformer, the optimized transformer has faster charging speed and better linearity in the charging experiments. The experimental results verify the validity and feasibility of the optimization method.关键词
