Interface Circuit Design of Resolver and Signal Processing based on AD2S1200
Wang Yao-nan · IEEE Transactions on Power Electronics · 2008
The revolver digital converter AD2S1200 is used to transform analog signals of revolver to digital signals for the purpose of digital siginal processing.The basic principle of the resolver is introduced.The interface circuit for resolver,as well as the interface circuit between AD2S1200 and TMS320F2808 DSP controller are designed.A stronger error-tolerant processing method of the position signal is proposed.The expetiment result shows that the design method is featured of high precision and reliability,good anti-jamming capabilities,and can completely meet high-speed motor control system.
