新型汽车设计需要具超低IQ的高压同步降压型转换器

汽车中非常复杂的电子系统之快速增加使得对电源管理IC的性能要求更高了。视电源在汽车电源总线上工作部位的不同,电源可能遇到停/启、冷车发动和负载突降情况,而且必须在这类情况发生时,能够自始至终准确地调节输出电压。此外,有些这类系统会以始终保持接通的备用模式工作,需要最小的电源电流。因此,最大限度地减小解决方案占板面积同时最大限度地提高效率也变得至关重要了。

Research on the On-line Monitoring System of Battery Power

Through the comparison of various acquisition technology and related technology theory of the existing scheme, the paper analyze and design the power battery testing platform of the data acquisition system, and give the research design scheme of the utility model through the design of the software on PC and CAN bus, which makes the full synchronization requirements acquisition unit; improve the linearity and stability of total voltage and current acquisition by the integrated circuit, and improve the system sampling rate, effectively complete the corresponding index. Finally, through experimental verification, to ensure the completion of the technical indicators.
