In　the　present　investigation,　a　simulation　of　the　dynamic　characteristics　of　a　high-speed　solenoid　valve　(HSV)　was　performed　using　the　finite-element　method　(FEM).　The　interrelation　between　power　losses　and　the　dynamic　response　of　the　HSV　was　investigated　based　on　the　FEM　simulation　model.　The　relationship　between　the　boost　voltage,　dynamic　response,　and　power　losses　was　established　according　to　the　energy　conversion　at　the　HSV　system.　The　simulation　results　indicated　that　as　the　boost　voltage　increases,　the　rising　rate　of　the　driving　current　at　the　solenoid　valve　increases　sharply,　which　favors　the　quick　opening　of　the　solenoid,　while　the　power　losses　caused　by　the　eddy　current　at　the　iron　core　increase　rapidly.　The　rapid　increase　in　the　energy　loss　of　the　eddy　current　was　the　main　factor　that　limited　the　effectiveness　of　reducing　the　opening　response　time　of　the　solenoid　valve　by　increasing　the　boost　voltage.　Regarding　the　energy　utilization,　an　optimal　boost　voltage　existed,　where　the　solenoid　valve　reached　the　highest　energy　utilization　efficiency.　(C)　2017　Elsevier　Ltd.　All　rights　reserved.
