Increasing the injection signal amplitude increases not only the acoustic noise and high‐frequency (HF) losses, but also the total harmonic distortion (THD) of the output voltage and current ripples. A new pulsating semi‐impulse signal injection method based on the current sensing technique is proposed for the sensorless control of interior permanent magnet synchronous motors (IPMSMs). The proposed method aims to control the motor speed and reduce some problems due to the HF signal injection involving acoustic noise, HF losses and THD of the output voltage. Taking into account the premium injection angle, these problems are reduced significantly as compared to those in conventional square‐wave methods. Hence, the proposed method increases the sensorless driver efficiency and its application scope. The effectiveness of the proposed method is then confirmed with computer simulation and experimental tests. Experimental comparisons at the same injection frequency and injection effective voltage show that the performance of the proposed method is beneficial. All experiments were performed on a IPMSM with V‐shaped PMs which is used in a refrigerator compressor. 09 17 2019 10 2019 3197 3207 10.1049/iet-pel.2018.6250 2 10.1002/crossmark_policy ietresearch.onlinelibrary.wiley.com true 2018-11-17 2019-07-22 2019-09-17 Korea Institute of Energy Technology Evaluation and Planning https://doi.org/10.13039/501100007053 http://onlinelibrary.wiley.com/termsAndConditions#vor 10.1049/iet-pel.2018.6250 https://ietresearch.onlinelibrary.wiley.com/doi/10.1049/iet-pel.2018.6250 https://ietresearch.onlinelibrary.wiley.com/doi/pdf/10.1049/iet-pel.2018.6250 https://onlinelibrary.wiley.com/doi/pdf/10.1049/iet-pel.2018.6250 https://onlinelibrary.wiley.com/doi/full-xml/10.1049/iet-pel.2018.6250 https://ieeexplore.ieee.org/document/8855179 10.1109/TIE.2010.2081960 10.1109/TPEL.2016.2569418 10.1109/TIA.2011.2126552 10.1109/TPEL.2013.2278103 10.1109/TIE.2016.2593657 10.1109/TIA.2013.2293000 10.1109/TPEL.2016.2620259 10.1109/TPEL.2015.2426200 10.1109/IAS.2003.1257695 10.1109/PEDSTC.2018.8343788 10.1109/ECCE.2015.7310450 AlaeiA.
