High performance operation of high-speed electric machine leads to a demand on high switching frequency, which results in inverter heating, short lifespan, large heat sink, etc. In this paper, high-speed permanent magnet synchronous machine drive with IGBT based three-level T-type inverter (3LT2I) and two-level inverter are investigated and the losses in the machine and inverter are compared. A 200kW...
With the increasing pressure on modern power converters towards higher efficiency and smaller volume, power electronic specialists are now even more obliged to power converter optimization. In this study, the optimal design of an 800W, hard switched step down converter is targeted. Switching frequency (f) and inductance (L) are selected as parameters for optimization. Interleaving, a technique widely...
The recently proposed current-fed quasi-Z-source inverter (QZSI) can buck/boost voltage and provide bidirectional power flow. A crucial criterion for the size of three phase PWM converters is the cooling of the power semiconductors and thus determination of power dissipation at certain operating points. A complete analytical calculation of the power loss for current-fed QZSI is presented. Inverter...
