Power Inverter Dead Time and Propagation Delay Specifica-tions

The HCPL-4504/0454/J454 and HCNW4504 include aspecificationintendedtohelpdesignersminimize“deadtime”intheirpowerinverterdesigns.Thenew“propaga-tiondelaydifference”specification(tPLH-tPHL)isusefulfordetermining not only how much optocoupler switch-ingdelayisneededtoprevent“shoot-through”current,butalsofordeterminingthebestachievableworst-casedeadtimeforagivendesign.

The difference between the maxi-mumandminimumvaluesdependsdirectlyonthetotalspreadinpropagationdelaysandsetsthelimitonhowgoodtheworst-casedeadtimecanbeforagivendesign.Therefore, optocouplers with tight propagation delayspecifications(andnotjustshorterdelaysorlowerpulse-widthdistortion)canachieveshortdeadtimesinpowerinverters.

It is importanttomaintainaccurateLEDturn-ondelaysbecause delays shorter than (tPLH-tPHL)max may allowshoot-throughcurrents,whilelongerdelayswillincreasetheworst-casedeadtime.

TheLEDsignaltoturnonQ2shouldbedelayedenoughso that an optocoupler with the very fastest turn-onpropagationdelay(tPHLmin)willneverturnonbeforeanoptocouplerwiththeveryslowestturn-offpropagationdelay(tPLHmax)turnsoff.Toensurethis,theturn-onoftheoptocoupler should be delayed by an amount no lessthan(tPLHmax-tPHLmin),whichalsohappenstobethemax-imumdatasheetvalueforthepropagationdelaydiffer-encespecification,(tPLH-tPHL).TheHCPL-4504/0454/J454andHCNW4504specifyamaximum(tPLH-tPHL)of1.3µsoveranoperatingtemperaturerangeof0-70°C.
