“…In another space vector PWM [3], [11] which is essentially space vector representation of Venturini's first method, it is possible to synthesize voltage vector at the machine terminals by using only rotating space vectors [4]. In this method, the instantaneous sum of voltages at the machine terminals is zero and hence elimination of switching common-mode voltage at the machine terminals can be achieved [12]. However, this strategy has a serious limitation; the maximum voltage ratio is limited to only 0.5, hence this strategy can not be used for most practical purposes.…”

In this paper, a new space vector PWM strategy for a matrix converter based open-end winding drive is presented. This modulation strategy enhances the capability of drive system to supply reactive power to the grid while eliminating switching common-mode voltage at the machine terminals. The enhanced reactive power support is possible due to the following new features of the proposed PWM strategy: 1) For a desired gridside power factor, the maximum available voltage at the machine terminals is higher than the maximum available voltage in conventional strategy, 2) For the same voltage at the machine terminals, lower (than conventional strategy) grid-side power factor is possible. Analytical expressions which show the relation between grid-side power factor and available voltage at the machine terminals are derived. Gain in voltage is compared with the previous method. Simulation results and experimental results of a hardware prototype are presented.

“…A method to design an integrated filter of matrix converter for drive application was reported which shown that it could meet strict EMI regulations with a small value of filter volume [11]. Additionally, several proposed technologies were reported to eliminate peak value of common-mode voltage in matrix converters [12][13][14][15]. However detailed studies on common-mode current caused by common-mode voltage on coupling paths in matrix converters are lacking.…”

This paper introduces an equivalent circuit analysis method to investigate common-mode effects in matrix converter applied in wind energy systems. Transfer characteristics of common-mode current against emission sources are analyzed in order to identify the coupling of transfer functions due to absence of DC link. The comprehensive analysis results provide insight into the common-mode current generation, coupling, and transmission. In addition, the matrix converter time-domain model is established with accurate parasitic parameters from experimental measurements. The validity and effectiveness of analysis method has been verified by timedomain simulation.

AC-AC converters (e.g. matrix converters) are mostly semiconductor solutions for applications where intermediate energy storage is eliminated. This paper summarizes the research done and being carried out at the University of Minnesota for applications in motor drives and power-electronic transformers with advanced features. This paper presents a carrier-based modulation method for matrix converters and its application during for both input unbalance and output over-modulation. Various topologies of matrix converter are described for both drives and power-electronic transformers. These topologies have some inherent benefits like common-mode voltage elimination across the bearings of the motor/generator and controllable power factor at the input side. Some of the described technologies require open-ended machines as load and thereby some advantages like enhanced output voltage (1.5 times the output of normal three terminal load) are achieved. 
