但IR2161提供软启(qi)动(dong)操作(zuo)，可以(yi)避免浪涌(yong)电(dian)(dian)(dian)(dian)流产生(sheng)。在(zai)(zai)(zai)灯(deng)(deng)启(qi)动(dong)期(qi)间，IR2161输(shu)出125kHz的(de)高(gao)频(pin)。由于系统(tong)中(zhong)(zhong)输(shu)出高(gao)频(pin)变(bian)(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)T1初级(ji)漏感是固(gu)定(ding)的(de)，在(zai)(zai)(zai)较(jiao)高(gao)的(de)频(pin)率下呈现较(jiao)高(gao)的(de)阻抗，初级(ji)绕组上的(de)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)(ya)(ya)较(jiao)低(di)(di)．致使变(bian)(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)输(shu)出电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)(ya)(ya)较(jiao)低(di)(di)，灯(deng)(deng)电(dian)(dian)(dian)(dian)流较(jiao)小，同时也避免了保护(hu)电(dian)(dian)(dian)(dian)路被(bei)触发。约经(jing)1s的(de)时间，电(dian)(dian)(dian)(dian)路以(yi)较(jiao)低(di)(di)频(pin)率运(yun)行。在(zai)(zai)(zai)此过(guo)程中(zhong)(zhong)，IC脚3外部电(dian)(dian)(dian)(dian)容CSD上的(de)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)(ya)(ya)从OV增加到5V。当空载(zai)时，VCSD=OV，振(zhen)(zhen)荡(dang)器(qi)(qi)(qi)(qi)频(pin)率约60kHz。在(zai)(zai)(zai)蕞大(da)(da)负载(zai)下，VCSD=5V，振(zhen)(zhen)荡(dang)器(qi)(qi)(qi)(qi)频(pin)率约30kHz。当输(shu)出短路时，大(da)(da)电(dian)(dian)(dian)(dian)流流过(guo)半桥，被(bei)RCS感测(ce)。只要IC脚4(CS)上电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)(ya)(ya)超过(guo)1V的(de)门(men)限电(dian)(dian)(dian)(dian)平持续(xu)50ms以(yi)上的(de)时间，系统(tong)将关闭。如果(guo)负载(zai)超过(guo)蕞大(da)(da)负载(zai)的(de)50%，IC脚4上的(de)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)(ya)(ya)将超过(guo)O5V较(jiao)低(di)(di)的(de)门(men)坎电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)(ya)(ya)，在(zai)(zai)(zai)经(jing)0．5S之(zhi)(zhi)后，系统(tong)将关闭。不论是短路保护(hu)还(hai)(hai)是过(guo)载(zai)保护(hu)，都能(neng)自动(dong)复位。IR2161还(hai)(hai)提供过(guo)热关闭功(gong)能(neng)。当芯片结(jie)温超过(guo)135℃的(de)过(guo)温度限制值(zhi)时，半桥开关将停止工作(zuo)，以(yi)避免MOSFET烧坏。电(dian)(dian)(dian)(dian)子(zi)变(bian)(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)用途编辑电(dian)(dian)(dian)(dian)子(zi)变(bian)(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)在(zai)(zai)(zai)传统(tong)照明(ming)灯(deng)(deng)具中(zhong)(zhong)的(de)应用十分普遍，如日光灯(deng)(deng)、台灯(deng)(deng)、节能(neng)灯(deng)(deng)、广告灯(deng)(deng)等等几乎(hu)都可以(yi)使用电(dian)(dian)(dian)(dian)子(zi)变(bian)(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)，并(bing)且(qie)采(cai)用电(dian)(dian)(dian)(dian)子(zi)变(bian)(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)之(zhi)(zhi)后，可以(yi)省(sheng)掉启(qi)动(dong)器(qi)(qi)(qi)(qi)。在(zai)(zai)(zai)LED照明(ming)中(zhong)(zhong)，新品也大(da)(da)都采(cai)用电(dian)(dian)(dian)(dian)子(zi)变(bian)(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)。主(zhu)要是电(dian)(dian)(dian)(dian)子(zi)变(bian)(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)在(zai)(zai)(zai)变(bian)(bian)(bian)压(ya)(ya)(ya)(ya)(ya)功(gong)能(neng)上，效(xiao)率高(gao)、成本底。浙江平板变(bian)(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)订(ding)做价格
