As　the　core　component　of　the　HVDC　transmission　converter　valve,　thyristors＇　reverse　recovery　characteristics　have　important　influence　on　electromagnetic　transient　characteristics　of　the　converter　valve,　and　are　also　the　theoretical　foundation　for　the　converter　valve　design,　manufacture,　operation　and　maintenance.　The　effects　of　forward　current,　absorption　circuit　parameters　and　current　change　rate　on　the　thyristors＇　reverse　recovery　characteristics　are　studied,　and　the　influence　mechanism　has　been　analyzed　by　experiments.　The　results　shows　that　the　change　of　the　forward　current　and　the　current　change　rate　can　lead　to　the　reverse　recovery　charge　change,　which　can　change　the　reverse　recovery　voltage　stress　of　thyristors.　The　greater　the　absorption　capacity,　the　smaller　the　reverse　recovery　voltage　press　of　thyristor,　and　when　the　absorption　capacity　is　constant,　there　is　the　only　absorption　resistor　of　the　thyristor　which　can　lead　to　the　minimal　reverse　recovery　voltage　overshoot　of　the　thyristor.
