摘要
对柴油机电子控制单元电源系统电路设计进行分析研究,重点介绍电源系统电路中过流保护、过压保护、防反接保护、抗干扰设计保护、电压检测保护等各种保护电路的设计原理、器件选型及应用、抗干扰性能设计等相关问题,最后得出较好的电源系统保护电路设计方案。
The author researches and analyses the power supply system of the ECU, which is used in the high- pressure common rail system. It focuses on the design principle, device selection and application, anti-interference capacity design of each protection circuit of the power system, which contains overcurrent protection, overvohage protection, anti-reverse polarity protection, anti-interference protection, and voltage detection protection. Finally it leads to a better power system protection circuit design.
