ADUM1400

四通道数字隔离器(4/0通道方向性)
Manufactured by:

产品详情

ADuM1400是采用4/0通道方向性的四通道数字隔离器,采用ADI公司iCoupler® 技术。 这些隔离器件将高速CMOS与单芯片空芯变压器技术融为一体,具有优于光耦合器等替代器件的出色性能特征。

iCoupler器件不用LED和光电二极管,因而不存在一般与光耦合器相关的设计困难。 简单的 iCoupler数字接口和稳定的性能特征,可消除光耦合器通常具有的电流传输比不确定、非线性传递函数以及温度和使用寿命影响等问题。

这些 iCoupler 产品不需要外部驱动器和其它分立器件。 此外,在信号数据速率相当的情况下,iCoupler 器件的功耗只有光耦合器的1/10至1/6。

ADuM140x系列隔离器提供四个独立的隔离通道,支持多种通道配置和数据速率(请参考数据手册“订购指南”部分)。 所有型号均可采用2.7 V至5.5 V电源电压工作,与低压系统兼容,并且能够跨越隔离栅实现电压转换功能。 此外,ADuM140x具有低脉冲宽度失真(CRW级小于2 ns)和严格的通道间匹配(CRW级小于2 ns)特性。 与其它光耦合器不同,ADuM140x隔离器具有已取得专利的刷新特性,可确保不存在输入逻辑转换时及缺少一个电源条件下的直流正确性。

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.
