压频变换器(VFC)输出频率范围的确定

The Determination of the Output Frequency Range of VFC

本文从压频变换器的后端出发,根据测量系统要求的响应时间和微机系统配置的计数器、计时频率等信息从测频率法和测周期法两个方面给出压频变换器输出频率的最佳范围,对压频变换器的电路设计具有非常实用的指导意义.同时给出一个舵角测量的应用实例,并从角度传感器选用、压频变换器设计和单片机系统三部分较为完整地介绍船舶舵角测量系统的应用设计过程.

Starting from the back end of the VFC converter,according to the measured response time,mi-crocomputer system counter,timing frequency and other information,the optimal range of the output freq-uency of the VFC converter is given from two aspects of measuring frequency method and measuring p-eriod method,which has guiding significance for the circuit design of the VFC converter.An applicatio-n example of ship rudder angle measurement is also presented,and the application design process is com-pletely introduced from angle sensor selection,VFC converter design and microcomputer system design.
