产品详情

ADG3308是一款双向电平转换器,内置8个双向通道,可用于多电压数字系统,如低压DSP控制器与高压器件之间的数据传输等。器件的内部结构允许执行双向电平转换,且无需借助额外的信号来设置转换方向。

通过施加于VCCA的电压,可设置器件A端的逻辑电平,VCCY则负责设置Y端的逻辑电平。为确保正常工作,VCCA必须始终低于VCCY。施加于器件A端的VCCA兼容逻辑信号,在Y端则以VCCY兼容电平出现。类似地,施加于器件Y端的VCCY兼容逻辑电平,在A端则以VCCA兼容逻辑电平出现。

使能引脚(EN)可提供A端和Y端引脚的三态工作模式。将EN引脚拉低时,两端的引脚均处于高阻抗状态。正常工作时,EN应驱动至高电平。

ADG3308提供紧凑式20引脚TSSOP和20引脚LFCSP两种封装。EN引脚以VCCY电源电压为基准。

ADG3308的保证工作电压范围为1.15 V至5.5 V,工作温度范围为−40°C至+85°C。

    EVAL-FMCMOTCON2 电路图

    产品详情

    The AD-FMCMOTCON2-EBZ is a complete high performance servo system on an FPGA Mezzanine Card (FMC) board, the purpose of which is to provide a complete motor drive system demonstrating efficient and high dynamic control of three phase PMSM and induction motors up to 48V and 20A.

    Two motors can be driven at the same time, each motor having its separate power supply. The system incorporates high quality power sources; reliable power, control, and feedback signals isolation; accurate measurement of motor current & voltage signals; high speed interfaces for control signals to allow fast controller response; industrial Ethernet high speed interfaces; single ended Hall, differential Hall, encoder and resolver interfaces; digital position sensors interface; flexible control with a FPGA/SoC interface.

    The kit consists of two boards: a controller board and a drive board. An optional AD-DYNO2-EBZ dynamometer can also be purchased through Avnet and is intended to be an extension of the drive system.

    Controller Board

    • Digital board for interfacing with the low and high voltage drive boards
    • Compatible with all Xilinx FPGA platforms with FMC LPC or HPC connectors
    • FMC signals voltage adaptation interface for seamless operation on all FMC voltage levels
    • Fully isolated digital control and feedback signals
    • Isolated Xilinx XADC interface
    • 2 x Gbit Ethernet PHYs for high speed industrial communication, with 3rd party EtherCAT support
    • Single ended Hall, Differential Hall, Encoder, Resolver interfaces
    • Digital sensors interfaces
      • EnDat
      • BISS Interface

    Drive Board

    • Drives motors up to 48V @ 20A
    • Drives 2 motors simultaneously
    • High frequency drive stage implemented with ADI isolated gate drivers
    • Supported motor types
      BLDC
      PMSM
      Brushed DC
      Stepper (bipolar / unipolar)
    • Integrated over current protection
    • Reverse voltage protection
    • Current and Voltage measurement using isolated ADCs
    • BEMF zero cross detection for sensorless control of PMSM or BLDC motors
    • Separate voltage supplies for the 2 motors so that the motors don't influence each other

    Dynamometer System with Embedded Control

    • Two BLDC motors connected by a rigid couple in a dyno setup, which can be used to test real-time motor control performance.
    • One BLDC motor acts as an electronically adjustable load and is driven by the embedded control system. This motor can be directly connected to the FMC motor drive to get complex / active loads. The load can be driven also by the AD-FMCMOTCON2-EBZ to implement dynamic load profiles.
    • The other BLDC motor is driven by the FMC motor drive.
    • Measurement and display of load motor current
    • Measurement and display of load motor speed
    • External control using Analog Discovery and MathWorks Instrumentation Control Toolbox

    Software:

    Example reference designs showing how to use the platform with Xilinx® FPGAs or SoCs and high performance control algorithms from Mathworks® are provided together with the hardware. Information on the FMC board, and how to use it, the design package that surrounds it, and the software which can make it work, can be found by clicking the software link.
