“…A topology of the single-leg matrix converter (MxC) is derived from a single-leg VSI converter system with input rectifier [1][2][3]. The analysis of such a MxC topology scheme has been done [4,5]. The advantages of those schematics are presented by the absence of the input rectifier and bulky filtering capacitor and consequently higher efficiency.…”

This paper deals with the control of current phase advancing in single-leg voltage source inverters (VSI) and matrix converters with a two-phase output. The phase shift of the current in the auxiliary phase is set with the use of switched capacitors. Two distinctive control methods are used for the current phase advancing, open-loop control and closed-loop control. In addition, a new averaging method is derived for the calculation of the switched capacitance used in the open-loop control. The practical use of the designed control methods with the switched capacitor is shown in simulations and experimental verifications on a single-leg matrix converter with a passive and active load (induction motor).

“…To save some amount of power switching elements, it is possible to use the one-leg connection of the converters. The basic configuration of single-leg MxC was derived from single-leg voltage source inverter [1], [4], and for the first time was published in 2015, [5] with analysis and modeling [8]. Preliminary comparison of a SPIM Drive Fed by VSI and MxC with Option of Speed Reduction has been made in [9].…”

“…Taking supply voltage between center tape of MxC and zero point of the motor the calculated current waveform is depicted in Figure II. It's clear that due to strongly non-harmonic voltage (86 % [9]) the current time waveform is also non-harmonic. To be the current sinusoidal under any load it should be used some of PWM methods or using L-C filter.…”

The paper deals with analysis and modelling of a new type of single-phase supplied AC/AC converter with two phase outputs. It consists of one-leg half-bridge matrix converter loaded by the resistive-inductive load in series connection. As harmonic analysis of the voltage of both phases gives very high value of total harmonic distortion (roughly 86 %) the current waveforms should be improved by using of serial L-C filter -which brings much lesser value acceptable for application. The simulation is resulting in a recommendation for the fair and right design of the converter, and demands to single-or two-phase input supply voltage, respectively, under passive R-L or motoric load.
