| Abstract: | In the development of new energy vehicle, the application of the new semiconductor SiC has brought the possibility of increasing the power density of the motor controller. In order to further improve the power density and control performance of the system, this paper studies a software-based resolver-to-digital converter (RDC) technology uses a phase-locked loop-based angle-tracking observer algorithm to collect position information. In the experiment, the most widely used hardware based RDC technology (AD2S1210 IC) was compared from several aspects. Experimental results show that this method has the advantages of high power density, low cost, high accuracy, and fast speed, and is not limited by resolution. |
