　　超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)波(bo)發(fa)(fa)生(sheng)器(qi)(qi)(qi)是(shi)(shi)一種將電(dian)(dian)能(neng)轉化為(wei)機(ji)械能(neng)并向超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)換能(neng)器(qi)(qi)(qi)提供信號的(de)轉換裝置(zhi)。它(ta)對超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)波(bo)清洗(xi)機(ji)的(de)清洗(xi)效果起著決定性(xing)的(de)作(zuo)(zuo)用。超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)波(bo)發(fa)(fa)生(sheng)器(qi)(qi)(qi)的(de)作(zuo)(zuo)用是(shi)(shi)將城市(shi)用電(dian)(dian)轉換成與超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)換能(neng)器(qi)(qi)(qi)相(xiang)匹配的(de)高頻(pin)交流(liu)信號，驅動超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)換能(neng)器(qi)(qi)(qi)工作(zuo)(zuo)。大(da)功率超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)電(dian)(dian)源(yuan)(yuan)在轉換效率方面一般采(cai)用開關(guan)電(dian)(dian)源(yuan)(yuan)的(de)電(dian)(dian)路形式。超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)波(bo)發(fa)(fa)生(sheng)器(qi)(qi)(qi)換能(neng)器(qi)(qi)(qi)電(dian)(dian)源(yuan)(yuan)分為(wei)自(zi)激電(dian)(dian)源(yuan)(yuan)和其(qi)它(ta)激勵電(dian)(dian)源(yuan)(yuan)。自(zi)激電(dian)(dian)源(yuan)(yuan)稱(cheng)為(wei)超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)模擬電(dian)(dian)源(yuan)(yuan)，其(qi)激勵電(dian)(dian)源(yuan)(yuan)稱(cheng)為(wei)超(chao)(chao)(chao)(chao)(chao)聲(sheng)(sheng)波(bo)發(fa)(fa)生(sheng)器(qi)(qi)(qi)換能(neng)器(qi)(qi)(qi)。

　　超聲(sheng)(sheng)波發生器換能器采(cai)用(yong)世界領先的其它沖(chong)擊電(dian)路(lu)結構，與(yu)自(zi)激振蕩電(dian)路(lu)結構相比，輸出功率提高(gao)10%以上。超聲(sheng)(sheng)波發生器換能器采(cai)用(yong)線(xian)(xian)性(xing)放大電(dian)路(lu)和(he)開關電(dian)源(yuan)電(dian)路(lu)。開關電(dian)源(yuan)電(dian)路(lu)的優(you)點：轉換效率高(gao)，所以大功率超聲(sheng)(sheng)電(dian)源(yuan)采(cai)用(yong)這種形式。線(xian)(xian)性(xing)電(dian)源(yuan)電(dian)路(lu)優(you)點：電(dian)路(lu)匹配(pei)要求不嚴格，工作頻率可連續(xu)快速變(bian)化。
