IS220PDOAH1B 逆變式模塊電源
IS220PDOAH1B 高頻逆變式整流焊機電源是一種高·能、·效、省材的新型焊機電源,代表了當今焊機電源的發展方向。由於IGBT大容量模塊的商用化,這種電源更有著廣闊的應用前景。
IS220PDOAH1B 逆變焊機電源大都採用交流-直流-交流-直流(AC-DC-AC-DC)變換的方法。50Hz交流電經全橋整流變成直流,IGBT組成的PWM高頻變換部分將直流電逆變成20kHz的高頻矩形波,經高頻變壓器耦合, 整流濾波後成為穩定的直流,供電弧使用。
IS220PDOAH1B 由於焊機電源的工作條件惡劣,頻繁的處於短路、燃弧、開路交替變化之中,因此高頻逆變式整流焊機電源的工作可靠性問題成為·關鍵的問題,也是用戶·關心的問題。
採用微處理器做為脈衝寬度調制(PWM)的相關控制器,通過對多參數、多信息的提取與分析,達到預知係統各種工作狀態的目的,進而提前對係統做出調整和處理,解決了大功率IGBT逆變電源可靠性。
IS220PDOAH1B 國外逆變焊機已可做到額定焊接電流300A,負載持續率60%,全載電壓60~75V,電流調節範圍5~300A,重量29kg。
IS220PDOAH1B Inverter module power supply
IS220PDOAH1B High-frequency inverter rectifier welding machine power supply is a new type of welding machine power supply with high performance, high efficiency and material saving, which represents the development direction of today's welding machine power supply. Due to the commercialization of IGBT large-capacity modules, this power supply has broad application prospects.
IS220PDOAH1B Most inverter welding machine power supplies adopt the AC-DC-AC-DC (AC-DC-AC-DC) conversion method. The 50Hz alternating current is converted into direct current through full-bridge rectification. The PWM high-frequency conversion part composed of IGBT inverts the direct current into a 20kHz high-frequency rectangular wave. After coupling with the high-frequency transformer, it becomes a stable direct current after rectification and filtering, and is used for power supply arc.
IS220PDOAH1B Due to the harsh working conditions of the welding machine power supply, which frequently undergoes alternating short circuit, arcing, and open circuit changes, the working reliability of the high-frequency inverter rectifier welding machine power supply has become the most critical issue and the issue that users are most concerned about. .
IS220PDOAH1B Using a microprocessor as the relevant controller of pulse width modulation (PWM), through the extraction and analysis of multi-parameters and multi-information, the purpose of predicting various working conditions of the system can be achieved, and the system can be adjusted and processed in advance to solve the problem. Improves the reliability of high-power IGBT inverter power supply.
IS220PDOAH1B Foreign inverter welding machines can achieve a rated welding current of 300A, a load duration of 60%, a full load voltage of 60~75V, a current adjustment range of 5~300A, and a weight of 29kg.
