| Abstract: | According to the EUP drive requirements of high-power diesel engine,the overall scheme of circuit was designed based on Peak&Hold drive.Then the design of rise voltage drive circuit was completed and verified in a high-power EUP.The result shows that the minimum operating interval of drive circuit is 5 ms.For the electromagnetic valve,the high-voltage peak current reaches 20 A,the maintaining current is 15 A,the action time is less than 200 μs and the low-voltage maintaining current is 8 A,which meets the drive requirement of EUP rise voltage. |
