电动伺服旋转变压器的激磁放大电路研究
Research on exciting amplification circuit of rotary transformer for electric servo system
摘要
Abstract
The rotary transformer can obtain the high position accuracy with strong enough exciting signal,while the de⁃coding chip provides poor exciting signal,it is necessary to design the amplifying circuit to amplify the exciting signal. On the basis of decoding chip AD2S1200,the exciting amplifying circuit of the rotary transformer TS2620N21E11 is studied. Four exciting amplifying circuits were designed,and their working principles are introduced in detail. The analysis results show that the ampli⁃fying circuit composed with the high output current amplifying circuit has simple structure but high cost;the power amplifying circuit with general operational amplifier and no output capacitance has slightly complex circuit structure but low cost. Both the simulation and experiment results verify that the exciting amplifying circuit is correct and practical.关键词
