高压共轨喷油器智能驱动仪的开发研究

Reach and Development of High Pression Common Rail Injector Intelligent Driver

针对高压共轨喷油器开发中需要灵活调整驱动电压和电流参数的要求,选用CY335芯片开发了一种智能驱动仪,介绍了智能驱动仪的硬件组成、工作原理和诊断保护等内容,试验结果表明:自主开发的智能驱动仪能够实现开发要求,集成度高、工作可靠,具有实际应用价值。

In the development of high pression common rail injector,it needs to adjust the parameter of driving voltage and current flexibly. This paper introduces the design of an intelligent driver based on CY335 which is a pre-drive IC. And it mainly introduces the intelligent driver's hardware constitution,operating principle and diagnosis,etc. By test it proves that the intelligent driver could satisfy the designing requirements,it has high integrated level and reliability. Also it has wide-ranging application foreground.
