abstract

  • Multiphase machines are considered for high power variable speed drive applications due to numerous advantages that they offer when compared to their three-phase counterparts. Multiphase VSI or CSI used to provide variable voltage and variable frequency supply with appropriate PWM control to multiphase machines. Carrier-based PWM and space vector PWM (SVPWM) are the most common options for controlling a multiphase converter. A new class of inverter called quasi impedance source (qZSI) employed mostly for solar PV applications, is presented in this paper for five-phase output. Although the application of multiphase inverters are mostly in motor drives, however, the proposed topology can be employed in conjunction with multiphase wind generator system as well. Another application of the proposed topology can be conceived in solar PV based multiphase water pumping solution. The major advantage of the proposed topology is the voltage boost and continuous source side current. This paper is aimed at providing boosted outputs of carrier-based PWM implementation of five-phase qZSI with coupled inductors with and without shoot-through states. The concept is verified by simulation using Matlab Simulink model. © 2013 IEEE.
