Opis:: The paper deals with two-phase one-leg matrix converter with minimum switching devices. Main emphasis is laid on modelling and simulation 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 LC filter – which brings much more suitable value of THD (5 % - 8 %) acceptable for application. Real simulation results using LT Spice circuit simulator under RL loading are given in the paper

Opis:: The paper deals with the new method of analysis, synthesis and experimentation of single-phase power active filters. By using a new particular transformation theory, the ordinary single-phase system can be transformed into an equivalent two-axes orthogonal one. The new original thought is based on the idea that ordinary single-phase quantity can be complemented bv fictitious second phase so that both of them will create an orthogonal system, as is usual in three-phase systems, in spite of [1]. Application of the above theory makes it possible to use complex methods of analysis as the instantaneous reactive power method, which have not been usable for single-phase systems so far. Both, the active and reactive powers can be determined by this way. Practical application of the method is outlined for the case of reference current determination for single-phase power active filter. The paper shows some examples of the simu-lution verification results, which proved a high accuracy and extremely fast response of the single-phase active filter with control, based on the introduced method. The effectiveness of proposed control algorithm is also demonstrated by experimental results, which were carried out on the single - phase active parallel filter, power rate of 25 kVA and controlled by 32 - bit Heating point digital signal processor TMS 320C31.
