Abstract: A accurate detection circuit for the PMSM drive system rotor position in electric vehicle was designed. It used the high reliability and low cost of new decoding chip AU6803 as the processor and mainly introduced the use of the AU6803 and the design of related peripheral circuit. After finishing hardware simulation analysis of the interface circuit based on the Cadence /Pspice software, the experiment of PMSM system was implemented to validated the design of interface circuit, and the experimental results confirm that the designed interface circuit has the following features such as simple, reliable and strong anti-interference abilities, and also accurately obtains rotor position of PMSM．
