ISOLATED INVERTER PLATFORM

Isolated Inverter Platform Evaluation Board

Buy Now View Details

Features and Benefits

The isolated inverter platform enables users to:

  • Evaluate ADI’s new, fully featured isolated gate drivers (ADuM4135) technology in a system-level application at realistic dc bus voltages (EV-MCS-ISOINVEP-Z)
  • Evaluate ADI simple dual isolated gate driver (ADuM4223) technology in a system-level application at realistic dc bus voltages (EV-MCS-ISOINV-Z)
  • Evaluate ADI sigma-delta modulators (AD7403) for voltage and current measurement or feedback in a realistic switching environment
  • Develop motor control algorithms utilizing ADI isolated sigma-delta current and voltage feedback
  • Test bench their motor control software/firmware with a flexible hardware development platform
  • Evaluate an elegant gate driver bias supply solution using the ADP1621

Product Details

The Isolated Inverter Platform is a rapid development system for hardware and/or software development in three-phase inverter applications, with a particular focus on motor control. Flexible evaluation of ADI isolation technology in a highly configurable system-oriented platform is enabled with multiple test-points, and connectivity options. An easy-plug connector allows controller connection to an ADSP-CM408 processor evaluation board, while additional 0.1” headers enable alternative connectivity to other processor or FPGA platforms. The benefits of ADI isolated sigma-delta converters for voltage and current measurement, isolated gate drivers, and power controllers can be explored in a full system application at dc bus levels up to 800V. There are 2 models available, isolated inverter platform, and isolated inverter platform with full featured IGBT drivers.

Solution Overview
The isolated inverter platform and isolated inverter platform with full featured IGBT drivers offer a power board that runs from a dc input and provides a three-phase variable frequency, variable voltage, and variable dead-time PWM output to a three-phase motor or load. The inverter is provided as an open loop platform, but feedback signals are provided to enable the application developer to close the control loop. For the isolated inverter platform (EV-MCS-ISOINV-Z), two isolated current,phase to phase and dc bus voltage feedback signals are provided to the control side of the board via sigma-delta modulators, and these can be used for development of control algorithms. The inverter is made up of a three-phase six-IGBT bridge, with the IGBTs rated at 1200V and driven by three dual isolated gate drivers (ADuM4223). For the isolated inverter platform with full featured IGBT drivers (EV-MCS-ISOINVEP-Z), three isolated phase current and dc bus voltage feedback signals are provided to the control side of the board via sigma-delta modulators, and these can be used for development of control algorithms. The inverter is made up of a three-phase six-IGBT bridge, with the IGBTs rated at 1200V and driven by six individual isolated gate drivers (ADuM4135) with desaturation protection and Miller clamp. For both platforms, a DC – rather than AC- input is provided to allow flexibility on the dc bus voltage level (rather than it being limited to the ac line peak).

The board is designed to work from a DC supply in the range 24Vdc-800Vdc.. The power board is rated up to 2kVA without forced air cooling. Additional power throughput can be achieved with fan cooling added. A series connected diode implements a half-wave rectifier at the input, so if needed, the power board can be driven from an AC supply. However output power is limited in this case. If a full AC front-end is required, the inverter platform can be utilized in conjunction with the ADP1047 evaluation board up to 300W, or the ADP1048 evaluation board up to 600W. An isolated I2C interface is provided on the inverter board so that the ADP104x evaluation board can be easily controlled by the same processor/FPGA interface. The inverter kit has the hardware and software required to spin a three-phase motor under open loop speed control in conjunction with an ADSP-CM408 EZ Kit. The demo software is provided as an IAR Embedded Workbench C project or an executable file which can be flashed to the ADSP-CM408 processor using the ADI serial boot-loader utility. A .NET-based graphical user interface (GUI) is provided to enable motor start-stop, open loop Volts/Hertz speed control, and data visualization.

Features and Benefits

This evaluation board is obsolete and no longer recommended.


The FMCMOTCON2 evaluation kit enables users to:

  • Model and implement motor control algorithms rapidly for high performance servo systems, incorporating system modelling and design concepts using Mathworks model based design
  • Reduce time needed to move a motor control system from concept to production, by providing a prototyping system to verify the hardware and control algorithms before moving to production stage.

Product Details

This evaluation board is obsolete and no longer recommended.


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.
