Therefore, the aim of this thesis is to propose a integrated SMPMSM drive to improve the above drawbacks. Basically, the major contributions of this thesis can be summarized as follows, First, the proposed integrated SMPMSM drive can obtain two different levels of dc-link voltage. Compare with the conventional SMPMSM control scheme with field-weakening control and MTPA operation, lower copper loss, good current transient performance, wider operational range and reduced sensitivity to the variation of dc-link voltage are achieved in the proposed integrate drive. Second, an integrated control strategy is also proposed to fully exhaust the capability of the integrated drive, and the proposed control strategy can be implemented with single low-cost DSP chip. Third, a DSP-based drive prototype is constructed according to the structure of the proposed power stage and integrate control strategy. Finally, the experimental results are given to verify the feasibility of the proposed integrated drive, and wide operation range, low copper loss, automatic and smooth transformation between different operational mode, fast dynamic response, and reduced sensitivity to the variation of dc-link voltage can be observed from the above experimental results.
