The demand for lightweight converters with high control performance and low acoustic noise, increased the switching frequencies of two-level low-voltage 3-phase converters over the last few years. For high switching frequencies, converter efficiency suffers and can be kept high only by employing cost-intensive switch technology such as SiC diodes or CoolMOS switches; therefore, conventional IGBT technology still prevails. In this paper, the alternative of using three-level T-type inverter for low-voltage applications is addressed, and the performance and competitiveness of the T-type inverter, in contrast with conventional two-level voltage source inverters in the same switching frequency, are analyzed in detail. The proposed systems are implemented to connect to a Permanent Magnet Synchronous Motor (PMSM), and Space Vector Modulation (SVM) is applied to the control circuits. The T-type converter basically combines the positive aspects of the two-level converter, such as low conduction losses, small part count, and a simple operation principle, with the advantages of the three-level converter, such as low switching losses and superior output voltage quality. Therefore, it is considered a natural alternative to two-level converters for specific applications.
