© 2017 IEEE. The Phase Shifted Carrier Pulse Width Modulation (PSC-PWM) technique is a commonly used modulation strategy for multilevel converters. The PSC-PWM technique offers great performance advantages such as equal switch utilization, equal DC link utilization and harmonic benefits. With any PWM converters or modulation strategies, current ripple is inevitably generated and should be minimized. In particular, the peak-to-peak current ripple plays an adverse role in power converters, if ignored the current ripple would deteriorate the performance of the converter and damage the switching devices if the ripple exceeds the operating current limit of the device. This paper offers a novel approach for evaluating the peak-to-peak current ripple of a PSC-PWM Multilevel Cascaded H-Bridge (MLCHB). It is shown that the proposed method can determine the peak-to-peak current ripple of the standard PSC-PWM as well as with common-mode injected modulation. A comparison is made between two MLCHB converters with different number of H-bridge cells and modulation indexes. Lastly simulation results of the proposed method are provided.

The rotor saliency of the axially laminated synchronous reluctance motor (SynRM) produces a square airgap flux density distribution. If a square current distribution interacts with this flux the SynRM generates its optimal torque. This paper extends previous work on the magnetic modelling of the SynRM. A design model is proposed which incorporates all rotor and stator dimensions. Saturation effects have also been included in the model. The key dimensions affecting SynRM performance are identified as rotor radius, rotor pole pitch, rotor steel : steel+fibre ratio, airgap, stator current density and stator slot opening. An iterative algorithm is determined for the design optimization process. This algorithm is simple enough to be implemented in a spreadsheet environment. The model is used to design a 5 kW motor with an optimal torque/unit mass ratio. The designed motor has a nine phase concentrated winding to approximate the ideal square current excitation. Finite element analysis and a static load test on the constructed machine confirm the model's predictions. In addition, optimal values for the key motor dimensions, over a range of motor sizes, are determined and discussed.
