产品详情

ADuM7640/ADuM7641/ADuM7642/ADuM7643是采用ADI公司iCoupler®技术的6通道数字隔离器。这些1kV数字隔离器件采用小型20引脚QSOP封装。在仅需功能隔离时,与2.5kV或5kV隔离解决方案相比,这些器件可节约空间且成本更低。

像ADI公司的许多隔离器一样,该产品系列采用3.0V至5.5V的电源电压,并且功耗极低,仅为其它数字隔离器的十分之一至六分之一。除此之外,DuM7640/ADuM7641/ADuM7642/ADuM7643还提供低脉冲宽度失真(C级小于6 ns)和逐通道毛刺滤波器以保护设备不受外来噪声干扰。四种通道方向组合提供1Mbps或25Mbps的最高数据速率。在没有输入电源的情况下,所有型号的缺省输出均为逻辑高电平状态。

应用
• 通用多通道隔离
• SPI接口/数据转换器隔离
• RS-232/RS-422/RS-485收发器
• 工业现场总线隔离

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.
