16-Bit, Isolated Sigma-Delta Modulator
The analog input is continuously sampled by a high performance analog modulator, and converted to a ones density digital output stream with a data rate of up to 20 MHz. The original information can be reconstructed with an appropriate digital filter to achieve 88 dB signal to noise ratio (SNR) at 78.1 kSPS. The serial input/output can use a 5 V or a 3 V supply (VDD2).
The serial interface is digitally isolated. High speed complementary metal oxide semiconductor (CMOS) technology, combined with monolithic transformer technology, means the on-chip isolation provides outstanding performance characteristics, superior to alternatives such as optocoupler devices. The AD7403 device is offered in a 16-lead, wide-body SOIC package and has an oper-ating temperature range of −40°C to +125°C. The AD7403-8 device is offered in an 8-lead, wide-body SOIC package and has an operating temperature range of −40°C to +105°C.

FLEXMC MOTOR CONTROL LOW VOLTAGE KIT
The FlexMC Motor Control Development PlatformTM is a rapid development system for any motor control solution. The FlexMC KitTM enables you to accelerate time-to-market and increase performance with powerful model-based design tools. This solution combines hardware and software with out-of-the-box functionality for a permanent magnet synchronous motor (PMSM) with hall sensor, encoder, or sensorless feedback.
The FlexMC Kit has the hardware and software required to spin the kit’s motor under open or closed loop speed control in conjunction with an ADSP-CM408 EZ Kit. The software is provided as 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, speed control, and data visualization. Sample C-code is also provided for open loop Volts/Hertz control of a motor.
The FlexMC Kit hardware comes in two variants. The kit option includes a PMSM motor with encoder, a 24V motor drive board, and a power supply. The board-only option includes the motor drive board only. In this case users can connect their own motor and power source. In both cases, the power board connects directly to an Analog Devices ADSP-CM408 Mixed-Signal Control Processor EZ Kit (sold separately). Easy connection to motors and the CM408 EZ Kit make this system perfect for your prototyping needs.
Additional rapid prototyping MATLAB/Simulink tools and support can be obtained by purchasing this kit from Boston Engineering

ISOLATED INVERTER PLATFORM
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.
