ABSTRACT

In this paper, when generating a reference signal for a PMSM resolver, a hardware and software configuration method that can simplify the complexity of filter circuits and insensitive to changes in filter circuit characteristics is presented by composing triple signals using the port characteristics of the MCU. Accordingly, we analyzed the characteristics of the existing resolver reference signal and the filter circuit required for it, presented hardware that forms a three-level voltage output using the triple state characteristics of the MCU, and presented a software algorithm for constructing a sine wave using this. In order to prove the performance of the proposed method, the experimental circuit was constructed and the experiment was conducted. As a result, it was confirmed that the filter circuit was simplified to the 2nd order, but the circuit elements did not require high precision, although using the same number of MCU ports.
