摘要： The presented invention generally relates to speech analysis and synthesis; more specifically, it concerns a method and apparatus for voiced/unvoiced segmentation and pitch period marking in the analysis of a complex signal. The pitch marking method comprises removing the signal offset, low-pass zero-phase filtering with cut-off frequency f LP , calculation of the short-time autocorrelation using a sliding window with a variable window size, defining the short-time pitch autocorrelation time lag, defining the bandpass filter coefficients based on the value of the short-time pitch autocorrelation time lag, filtering the speech signal with an adaptive zero-phase bandpass filter with central frequency F cf , where the filter output signal is a pitch waveform, defining the pitch marks of the pitch signal by extracting the half periods of the pitch waveform, defining the pitch segment, and mapping the pitch marks of the pitch waveform onto the pitch marks of the speech signal. The method can further denote the pitch mark as a negative peak within the pitch segment, as a positive peak, or as the start and end sample of the speech period within which the positive and negative peaks appear. Voiced/unvoiced speech detection is performed using the thresholding method. The short-time absolute amplitude average of the zero-phase low-pass filtered signal and short-time pitch autocorrelation time lags are used as criteria for voiced/unvoiced segment detection and marking.

摘要： The invention solves the technical problem of the too long connections between the output from the secondary winding and an output rectifier also reducing the need for intensive cooling of rectifier means by integrating the rectifier means in the form of power diodes or MOSFET transistors into the parts of the secondary winding, where the arrangement is not more complex compared to the conventional solutions, however, it enables substantially shorter output connections. The proposed modified structure changes the electrical parameters of the welding system in such a way that, despite the required unchanged maximum value of the welding current and the use of rectifier means in the form of power diodes or MOSFET transistors, it is possible to further reduce electrical losses in secondary connections that become shorter, while simplifying also the cooling of rectifier means in the form of power diode or MOSFET transistors, which, with the proposed integration of secondary windings with output rectifier means in the form of power diode or MOSFET transistors, is cooled indirectly simultaneously with the cooling of the secondary winding. The proposed embodiment allows a significant increase in the power density of the welding transformer with an output rectifier. Because of the change in the electrical properties of the secondary part of the system, it is also possible to operate at slightly higher frequencies than 1 kHz, without parallelizing the secondary winding.

摘要： Arrangement of a transformer with an output rectifier (30) comprising at least one primary winding (231) that consists of at least one segment made with several turns, wound at a suitable distance around the transformer axis (300), an iron core (236) electrically isolated from said primary winding, at least one secondary winding (233) electrically isolated from said primary winding and said iron core, comprising a first part (234) of said at least one secondary winding and a second part (235) of said at least one secondary winding, wherein both are wound at appropriate distances around the transformer axis (300), between which at least one primary winding coil is arranged, wherein said primary winding and said secondary winding overlap along the axis (500) in a part surrounded by an iron core and further, wherein the said primary winding and the said secondary winding in the part of the winding heads, which are not surrounded by the iron core, overlap only partially or do not overlap, which allows straight and short arrangement of the connections of an output rectifier in the direction of the axis (500).
As a result of the proposed transformer arrangement improved electromagnetic properties of the welding system are obtained, which provides a more homogeneous distribution of magnetic field in the iron core and a homogeneous distribution of electric currents in conductive parts, which affects the reduction of transformer power loss and operation with the higher frequency of the supply voltage. The arrangement of the secondary winding according to the present invention at the same time enables a much simpler production of the cooling of the welding transformer with output rectifier by liquid coolant by making bores of the adequate dimensions.

摘要： A device and a procedure is presented for saturation detection of a welding transformer's iron core that solves the technical problem of the saturation detection of the welding transformers' iron cores by utilising measurement of the primary current of the transformer. The existing solutions are based on the incorporation of additional sensors hence the device's structure is modified. Amongst other consequences, these modifications may alter the properties of the device, increase its complexity, increase the production costs and reduce the robustness of the entire welding system. The presented technical problem is solved in an effective and inexpensive way that is based on an analysis of the measured primary current of the welding transformer. Using utilisation of the proposed solutions, additional sensors arc unnecessary as measurement of the primary current is needed in any case due to other reasons, such as control of the welding current, protecaion, diagnostics, etc. In this way, the additional components within the welding systems arc unnecessary. Therefore, all negative effects and aspects of usage of these components involving additional sensors and auxiliary devices for the saturation detection of thc magnetic cores of the welding transformers are avoided.

摘要： Izvedba transformatorja z izhodnim usmernikom (30) obsegajoč vsaj eno primarno navitje (231), obseženo iz vsaj ene plasti, ki je izvedena z več ovoji, nameščena v ustrezni razdalji okrog transformatoreve osi (300), železno jedro (236), električno izolirano od omenjenega primarnega navitja, vsaj eno sekundarno navitje (233), električno izolirano od omenjenega primarnega navitja in od omenjenega železnega jedra, obsegajoče prvi del (234) omenjenega vsaj enega sekundarnega navitja in drugi del (235)omenjenega vsaj enega sekundarnega navitja, kjer sta oba nameščena v ustreznih razdaljah okrog transformatoreve osi (300), med katera je razporejeno omenjeno vsaj eno primarno navitje, kjer se omenjeno primarno navitje in omenjeno sekundarno navitje prekrivata vzdolž osi (500) v delu, ki ga oklepa železno jedro in nadalje, kjer se omenjeno primarno navitje in omenjeno sekundarno navitje v delu glav navitij, ki jih omenjeno železno jedro ne oklepa, prekrivata samo delno ali pa se ne prekrivata, kar omogočaravno in kratko izvedbo priključkov izhodnega usmernika v smeri osi (500). Posledica predložene izvedbe transformatorja omogoča ustrezne magnetne in električne lastnosti sistema, ki zagotavljajo bolj homogeno porazdelitev magnetnih polij in homogeno porazdelitev električnih tokov v prevodnih delih, kar vpliva na zmanjšanje izgub v transformatorju in povečanje sposobnosti napajanja primarne strani transformatorja z napetostmi višje frekvence. Izvedba sekundarnega navitja po predloženem izumu pa hkratiomogoča bistveno enostavnejšo izdelavo vodnega hlajenja varilnega transformatorja z izdelavo izvrtin ustreznih dimenzij.
