Over the years, industrial processes, renewable energy systems and electrification of transport systems have been pushing power electronics equipment towards higher power ratings, quality and faster dynamics. In this context, several multilevel converter structures were developed and became popular, such as neutral-point-clamped, flying capacitor and cascaded half-bridge. This paper presents a generalized n-level converter using the multicell flying capacitor structure in an open-end winding configuration. A mathematical analysis shows that the proposed system presents the same output voltages as a traditional Δ/Y structure, but with less energy storage in the flying capacitors. The correlation with the traditional structure allows the use of an optimized modulation technique developed for the flying capacitor converter. It results in a voltage output with optimized harmonics, keeps the losses evenly distributed among the switching devices, and balances the voltages in the flying capacitors. Experimental results from a three-level conversion system and simulation results from a five-level structure demonstrate the features of the proposed topology.

With the increasing demand for industrial processes for power rating, quality and faster dynamics, multilevel converters and structures have been developed and became popular. Among them, the open-end winding topology is an advantageous structure for its lower device count and switching redundancy. This paper presents a vector modulation technique for one of these systems, which employs a pair of two-level converters, being equivalent to a traditional three-level system. The strategy uses the nearest space vectors to the reference in order ensure a good power quality on the output. Its main features are the balance of commutations among devices, its constant switching rate and the higher frequency current ripple. The characteristics of the fixed switching patterns to obtain the best quality on the output are presented along with simulation results that demonstrate the accomplishment of the strategy goals.

This paper proposes a new method for online identification of stator winding temperature for an open-end winding (OEW) permanent magnet synchronous motor (PMSM). The method exploits the zero sequence current (ZSC) due to the third harmonic back electromotive force (EMF) circulating in the system in order to estimate the phase resistance, which, in turn, is used to derive the winding temperature. In order to do this a proposed idea of maximum zero sequence current amplitude along with the actual ZSC amplitude and the electrical speed of the motor is used. The temperature is estimated without any additional sensors in a wide operating speed range. A single synchronous phase-locked loop (PLL) is utilised in order to obtain the required parameters. The independence of the rotor position grants the possibility for the exploitation of the proposed winding temperature estimation method in a variety of control techniques including the sensorless control to increase the robustness of the overall system.
