style="text-indent:25px">變頻器電源主要用于交流電機(jī)的變頻調(diào)速,其在電氣傳動系統(tǒng)中占據(jù)的地位日趨重要,已獲得巨大的節(jié)能效果。變頻器電源主電路均采用交流-直流-交流方案。工頻電源通過整流器變成固定的直流電壓,然后由大功率晶體管或IGBT組成的PWM高頻變換器, 將直流電壓逆變成電壓、頻率可變的交流輸出,電源輸出波形近似于正弦波,用于驅(qū)動交流異步電動機(jī)實(shí)現(xiàn)無級調(diào)速。高頻逆變式整流焊機(jī)電源是一種高性能、高效、省材的新型焊機(jī)電源,替代了當(dāng)今焊機(jī)電源的發(fā)展方向。由于IGBT大容量模塊的商用化,這種電源更有著廣闊的應(yīng)用前景。逆變焊機(jī)電源大都采用交流-直流-交流-直流(AC-DC-AC-DC)變換的方法。50Hz交流電經(jīng)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(jīng)高頻變壓器耦合, 整流濾波后成為穩(wěn)定的直流,供電弧使用。輸出有單路輸出，雙路輸出及多路輸出。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河南DCDC電源模塊有哪些優(yōu)勢,DCDC電源模塊"
