Power　electronic　module　is　the　core　component　of　a　hybrid　DC　circuit　breaker　(HDCCB)　to　break　the　fault　current,　which　has　an　important　influence　on　the　breaking　characteristics　of　HDCCB.　Integrated　gate　commutated　thyristor　(IGCT)　has　the　advantages　of　large　capacity,　low　on-state　voltage,　fast　turn-off　speed　and　strong　anti-surge　capability.　It　is　widely　used　as　a　core　turn-off　device　in　power　electronic　modules.　For　this　reason,　a　parallel　IGCTs　module　is　designed　for　DC　breaking　conditions.　Based　on　theoretical　analysis　and　experimental　verification,　the　influence　rules　of　on-state　current　sharing　of　parallel　IGCTs　under　different　current　rising　rates,　clamping　forces　and　wiring　modes　are　obtained.　A　control　method　for　parallel　IGCTs　current　sharing　during　turning　off　is　proposed.　The　results　show　that　the　on-state　current　sharing　of　the　parallel　IGCTs　is　mainly　affected　by　the　IGCT　device＇s　parameters　of　threshold　voltage　and　slope　resistance.　And　the　greater　the　clamping　force　is,　the　smaller　the　slope　resistance　will　be.　The　current　sharing　coefficient　of　parallel　IGCTs　of　wiring　mode　of　same　side　is　greater　than　that　of　the　opposite　side.　By　controlling　the　turn-off　timing　of　the　parallel　IGCTs,　the　instantaneous　power　distribution　imbalance　during　the　turn-off　process　can　be　improved.　The　turn-off　capability　and　reliability　of　module　can　also　be　improved.　©　2020,　High　Voltage　Engineering　Editorial　Department　of　CEPRI.　All　right　reserved.
