position resolver
2.Decoding resolver signals is realized by resolver-to-digital conversion IC AD2S90, and it has been implemented in the PMSM controller of the distributed driving EV. TMS320F2812 DSP solution using oversampling and digital filter for obtaining resolver angular position and speed has been proposed in this paper.
3.For the powerfully adaptive work ability of resolver in the complex and harsh condition, in the paper the resolver is applied to the AC drive system of the cross-country electrical vehicle to realize the accurate signal measurement of induction motor rotor position. The design of the interface circuit based on AU6802N1 of RDC chip is given.
