| Abstract: | According to the requirements of an electronically controlled unit pump,an intelligent driving module based on IC UC3843 was developed.This module can implement the function of current rising and holding by using the technology of high side and low side driving and the theory of circuit feedback.The experimental results show that using this module a peak rising current(16A) can be reached within 0.2ms and the minimum work interval is 4ms.The intelligent driving module can meet the requirements of electronic... |
