摘要
无接触供电系统采用疏松耦合变压器传输能量,和传统变压器相比,其耦合系数不高,因此传输效率较低,无接触供电系统传输效率的提高一直是制约其设计应用的瓶颈。本文从无接触变压器的一次、二次侧的逆变电路,一次、二次侧的无功补偿方式和无接触变压器本身等方面分析了影响系统效率的主要因素,为系统效率的提高提供了参考价值。
The loosely coupled transformer is used in the contactless energy transmission system. Compared to the conventional transformer, its coupling coefficient is not high, which leads to low energy transmission efficiency. Thus how to improve the efficiency is always the bottleneck problem in the system design and application. The paper analyzes the main influencing factors which include the primary and secondary inverter circuit, the primary and secondary compensation mode, and the contactless transformer itself, and then provides reference value to improve system efficiency.
