描述

根據(jù)柵極電壓與柵極電容的乘積為柵極電荷Q則上式可轉(zhuǎn)化為T=Q/I.本設(shè)計(jì)中功率MOSFET采用IR公司的IRF3710S功率MOSFET芯片，從其datasheet可以得到MOSFET的柵極電荷為26 nC,導(dǎo)通/截止時(shí)間為106 ns,可以得到峰值驅(qū)動(dòng)電流為，驅(qū)動(dòng)電壓為12 V,本設(shè)計(jì)驅(qū)動(dòng)芯片采用IR公司的IR2130驅(qū)動(dòng)模塊，該芯片可用來驅(qū)動(dòng)工作在母電壓不高于600 V的電路中的功率MOS門器件，其可輸出的最大正向峰值驅(qū)動(dòng)電流為250mA,輸出驅(qū)動(dòng)電壓為10~20V而反向峰值驅(qū)動(dòng)電流為500 mA.它內(nèi)部設(shè)計(jì)有過流、過壓及欠壓保護(hù)、封鎖和指示網(wǎng)絡(luò)，使用戶可方便的用來保護(hù)被驅(qū)動(dòng)的MOS門功率管，加之內(nèi)部自舉技術(shù)的巧妙運(yùn)用使其可用于高壓系統(tǒng)，它還可對(duì)同一橋臂上下2個(gè)功率器件的門極驅(qū)動(dòng)信號(hào)產(chǎn)生2μs互鎖延時(shí)時(shí)間。它自身工作和電源電壓的范圍較寬（3~20 V），在它的內(nèi)部還設(shè)計(jì)有與被驅(qū)動(dòng)的功率器件所通過的電流成線性關(guān)系的電流放大器，電路設(shè)計(jì)還保證了內(nèi)部的3個(gè)通道的高壓側(cè)驅(qū)動(dòng)器和低壓側(cè)驅(qū)動(dòng)器可單獨(dú)使用，亦可只用其內(nèi)部的3個(gè)低壓側(cè)驅(qū)動(dòng)器，并且輸入信號(hào)與TTL及COMS電平兼容。
