Special Issue Information

Dear Colleagues,

You are invited to submit your original research or review papers to this Special Issue on “The impact of power electronic converter switching on multiphase drive systems” in Electronics.

The power electronic converter is the main part in a multiphase drive system that is used in applications, such as electrical vehicle, hospital and military applications. The switching frequency of the power converter has a great impact on the obtained machine performance. The efficiency and the torque density of the drive system are highly dependent on the power converter switching. With the rapid progress of power electronics, this impact could be minimized.

The main objective of this Special Issue is to optimally select the optimal switching or design a power converter that has a smaller impact on machine performance. Moreover, this impact is an important one to consider, especially under the fault condition. This is not limited to the type of machine or the type of the power converter. The topics of interest include, but are not limited to:

  • Power converter topologies and associated control and modulation techniques.
  • Modeling and switching enhancement techniques for power converters.
  • New technologies in multiphase drives.
  • Fault detection and diagnosis.
  • Switching losses in power converter.

Multiphase drives have received a lot of interest because of their several features over traditional three-phase systems for high-power applications. Pulse-width modulation (PWM) approaches are necessary to regulate the supply for multiphase ac drives. As a result, it is vital to continually improve the modulation and control approaches used to upgrade output power converters’ quality. This paper offers a comparative analysis of the 2L + 2M and 6L space vector pulse-width modulation (SVPWM) techniques applied to a five-phase two-level voltage source inverter (VSI) fed an inductive (R-L) load. The comparative evaluation is based on measuring the inverter switching losses, the total harmonic distortion (THD) values, and the common mode voltage (CMV) under different operation scenarios. A system model is carried out by MATLAB/Simulink. An experimental prototype is constructed in the lab to validate the theoretical analysis. Simulation results for the system based on the two SVPWM techniques are obtained at different modulation indices and different output frequencies and are confirmed by the experimental results. It has been found that the peak-to-peak CMV of the 6L method is 80% lower than that of the 2L + 2M method. Moreover, 6L SVPWM offers better DC-link utilization compared to 2L + 2M SVPWM. Full article

This article presents and analyzes a three-to-five-phase indirect matrix converter (IMC) structure for directly supplying a five-phase static R–L load from a three-phase supply. The IMC topology offers a lower number of switches, a simple commutation procedure and a cost-effective clamping circuit in comparison to the direct matrix converter (DMC). A simple clamping circuit with one ultrafast diode and one small capacitor is proposed to protect the switches of the IMC from overvoltage. The issues of powering up the IMC with the simple clamping circuit is discussed in detail. The instructions for the safe start-up of the IMC with the proposed clamping circuit is introduced based on the simulated and the measured analyses. Moreover, a carrier-based pulse-width-modulation (CBPWM) method is also presented in order to control the switches of the IMC. The presented CBPWM method creates PWM pulses for both the inverter and the rectifier legs by using only one symmetric and triangular carrier signal. Finally, experimental and simulation testing with a five-phase R–L load demonstrate the viability and the efficiency of the introduced CBPWM algorithm for the suggested IMC. Full article
