This paper focuses on acoustic noise emissions caused by the transformer that operates as a part of DC/DC converter installed in a resistance spot welding system (RSWS). The discussed RSWS contains a three-phase input rectifier, an inverter, an iron core welding transformer with one primary and two secondary winding and two output rectifier diodes connected to the transformer’s secondary windings. In the case study, two different methods are applied to generate the inverter output voltage, which supplies the transformer’s primary winding. Considering possible origins of acoustic noise emission in the discussed transformer and based on performed simulations and measurements, the paper explains while the two applied voltage generation methods influence the acoustic noise emissions caused by the transformer differently.

W artykule opisano zagadnienie emisji hałasu przez transformator pracujący w układzie przetwornicy DC/DC w spawarce punktowej (ang. Resistance Spot Welding - RSW). Omawiana spawarka składa się z prostownika trójfazowego, falownika i transformatora z rdzeniem żelaznym. W badaniach wykorzystano dwie metody generowania napięcia wyjściowego falownika, zasilającego transformator i określono wpływ każdej z nich na emisję hałasów.
