结合变压器T网络模型的具有可变恒压增益特性的补偿网络参数确定新方法
A New Compensation Network Parameters Design Method With Variable Constant Voltage Gain Characteristics Based on Transformer T model
摘要
Abstract
This paper analyzed the coupled inductor model and the transformer T model of the magnetic coupling system in the wireless power transfer (WPT) based on the circuit theory.The principle of the different equivalent ratio by the same magnetic coupling system was got.And a new idea is proposed in which any constant WPT voltage gain can be got by compensation network design for a given magnetic coupling system.According to the multi-solutions of the transformer T model (including the equivalent leakage inductance in primary winding Lpk,the equivalent leakage inductance in secondary winding Lsk,the equivalent exaction inductance Lra and the equivalent ration n),the relationship between the Lpk,Lsk,Lm and n were established.By designing the compensation parameters for the resonant compensation of the corresponding equivalent leakage inductance at different equivalent ratio n,the WPT system could obtain variable voltage gain.The design concept is clear and the model is simple which can help to effectively broaden the range of output voltage gain.With the same input,output and frequency specification,the winding turns and the size of the magnetic coupling system can be reduced which is good for the footprint reduction of the magnetic coupling system.Finally,the experiment results verified the theory analysis to be correct and useful.关键词
