  1. The variable polarity power supply circuit uses two stages full - bridge inverter, the former inverter is regarded as a constant - current source with fast dynamic response, and supplys energy for the second one, and the latter one is to produce variable polarity current excellently, and low - frequency pulse current by variable polarity power supply is used to reduce input energy and control the shape of weld bead while welding. a series of high - frequency pulse current is superposed on direct - current - electrode - negative ( dcen ) current through the high - frequency pulse power supply, which is used to compress the arc and improve process of crystallization

    其中變極性電源採用二次全橋逆變結構，一次逆變提供快速的響應速率並給二次逆變提供能量，二次逆變提供良好的變極性性能，使輸出能量最優化，並用其低頻電流特性減小電弧線能量，控制焊縫成形;高頻脈沖電源提供的高頻電流疊加在反極性電流dcen上，利用電流的高頻特性壓縮電弧，改善焊縫金屬結晶過程。
  2. After debugging the waveform control system and man - machine interface system, we program constant - current control software and research respectively the current and voltage step response of power source. at last, the carbon dioxide welding method is realized in the welding machine controlled by the waveform control program. the simulated load test is also made here

    本文在完成所設計的波形控制系統和人機介面交互系統的調試后，首先編寫軟體實現了電源的恆流控制，並研究了該電源的電流、電壓的動態響應性能，最後，編寫控制軟體實現了雙斜率波形控制co2焊的功能並進行了模擬短路過渡負載試驗。
