产品详情

ADuM7223是一款4 A隔离式半桥栅极驱动器,采用ADI公司iCoupler®技术,提供独立且隔离的高端和低端输出。 这些隔离器件将高速CMOS与单芯片变压器技术融为一体,具有优于脉冲变压器和非隔离栅极驱动器组合等替代器件的出色性能特征。 通过在单封装内集成隔离器和驱动器,传播延迟最大值仅为60 ns,而通道间的传播偏斜最大值仅为7 ns。

ADuM7223提供两个独立的隔离通道。 ADuM7223采用3.0 V至5.5 V电源电压工作,可与低压系统兼容。 输出电压为4.5 V至18 V宽范围,并提供3种输出电压版本。 5 x 5 mm、LGA封装提供2500 V DC PEAK工作电压(输入至输出以及输出至输出)。

与采用高压电平转换方法的栅极驱动器相比,这些栅极驱动器的输入与各输出之间具有真电流隔离优势。 因此,这些栅极驱动器可以在很宽的正或负切换电压范围内,可靠地控制IGBT/MOSFET配置的开关特性。

EVAL-ADUM7223 电路图

产品详情

EVAL-ADUM7223EBZ支持ADuM7223隔离式精密半桥驱动器。由于评估板尺寸支持采用TO-252封装的IGBT和MOSFET,因此ADuM7223可通过很多不同的功率器件来评估。评估板还允许高端电源自举至低端电源。

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.
