英文摘要：

To solve the problem,a new constant current source drive circuit was proposed in this paper. The inductance＇s current is discontinuous,and this can reduce the unnecessary conduction losses compared with the continuous inductance current. The logic control is simple,flexible,easy to implement and high reliable. The operating principles and parameters＇ designing of the drive circuit was elaborated. A test,on a 100 V input /300 V output /400 W rated power Boost circuit,showed that the system＇s efficiency has increased by 1% under full load compared to that with traditional drive circuit.
