Abstract :
In this paper, an all-digital resolver-to-digital converter is presented. Using oversampling and frequency shifts techniques, along with a synchronous rotating reference frame based PLL, an accurate and fast tracking resolver-to-digital converter is presented. With the use of all these combined techniques, and using a standard DSP with a 10 bits ADC, resolutions of up to 12 bits are feasible. This paper presents the main techniques, simulation and experimental results
