Opis:This paper deals with the acoustic noise emissions caused by the transformer operating as a part of DC/DC converter in an industrial resistance spot welding system. The discussed DC/DC converter is schematically shown in Fig. 1. The three-phase alternating voltages (u1, u2 and u3) are rectified and smoothed in order to obtain almost constant DC-bus voltage UDC. The H-bridge inverter is used to supply the transformerćs primary winding with voltage pulses uH. The two transformerćs secondary windings are connected to the two output rectifier diodes (D1 and D2) which provide the direct welding current iL flowing through the load represented by LL and RL. A new control scheme forresistance spot welding systems was proposed in [1,2]. During the testing of the proposed control scheme it became evident that the proposed control scheme not only improves utilization of the iron core and prevent it from becoming saturated, but also substantially reduces the acoustic noise emissions caused by the transformer. The reasons for reduction of acoustic noise emission are discussed in this paper.
