针对新型逆变焊接电源电抗器的小型化、轻量化的发展需求,以及脉冲焊接时电流爬升和下降缓慢、电弧跟随性差等问题,提出使用一种新型磁心材料的电抗器。该电抗器磁心为NS类铁硅铝磁粉心,采用环形结构,根据不同的焊机类型和焊机规格,可以通过叠加环形磁心的个数或改变绕制圈数来满足焊接需求。采用一个新型材料的电抗器可以替代原来串联的一个开环电抗器和一个闭环电抗器,使电抗器体积和质量减小20%,且实现了电抗器磁心物料的统一。使用新型材料电抗器磁心可以提高脉冲焊接电流爬升和下降的响应速度及电弧跟随性,但会导致脉冲峰值电流的稳定性降低,因此又提出了将峰值电压反馈和电流反馈共同作用于脉冲峰值电流稳定阶段的新型脉冲控制算法,从而保证了脉冲焊接的稳定性。
In view of the development demand of miniaturization and light weight of the reactor of new inverter welding power supply, and the problems such as slow current climbing and falling and poor arc following during pulse welding, a new type of reactor with magnetic core material is presented. The magnetic core of the reactor is NS ferrosilica-aluminum magnetic powder core with ring structure. According to different welding machine types and welding machine specifications, the welding requirements can be met by adding the number of ring cores or changing the number of winding. A new type of reactor can replace one open loop reactor and one closed loop reactor in series, reduce the volume and weight of the reactor by 20%, and realize the unification of the reactor core materials. Using this reactor can improve the response speed of pulse welding current climbing and falling and arc following, but will lead to the decrease of the stability of pulse peak current, so a new pulse control algorithm based on peak voltage feedback and current feedback is proposed to ensure the stability of pulse welding.
