  • 1 Introduction The Quanser QNET Energy Conversion Board for NI ELVIS with ELVIS RIO Control Module is pictured in Figure 1.1. It is a reconfigurable system designed to teach the fundamentals of energy conversion across the electrical and mechanical domains. The modular system supports a number of different configurations and measurements of key parameters are achievable using the resources on the ELVIS RIO. Example experiments include open and closed loop SMPS (switched-mode power supply) control, 3-phase power generation, rectification, inverters, and power system integration and applications.

    The main QNET Energy Conversion features include:

    • Linear power amplifier

    • Mechanically coupled motor assembly (3-phase generator)

    • Rectifier

    • SMPS with configurable buck or boost topology

    • Inverter and transformer

    • Linear current load

    This equipment is designed to be used for educational and research purposes and is not intended for use by the general public. The user is responsible to ensure that the equipment will be used by technically qualified personnel only.

    QNET ENERGY CONVERSION - User Manual v 1.0

  • 2 System Hardware 2.1 System Schematic The QNET Energy Conversion provides an integrated communication interface with the NI ELVIS RIO Control Module. The interaction between the different system components on the QNET Energy Conversion is illustrated in Figure 2.1. The NI ELVIS RIO Control Module is interfaced to the PC or laptop via USB link. The NI ELVIS RIO Control Module provides command signals to the QNET Energy Conversion components. An on board supervisor is used to safeguard the hardware and to set the mode of operation.

  • Caution Components can get hot near the upper right corner of the board.

    2.3.1 Linear Amplifier

    The QNET Energy Conversion uses a power op amp to supply either the DC motor or the SMPS, depending on the mode of operation. It has a voltage compliance of 0 to 20V.

    2.3.2 3-phase AC Generator and Rectifier

    The QNET Energy Conversion uses the Anaheim Automation BLWR11D-24V-10000 brushless DC Motor as a 3-phase AC Generator. The specification sheet can be found at: Anaheim Automation BLWR11D-24V-10000.

    The generator is driven using a Micro-drives M2232U-24-GS-050 brushed DC Motor. The specification sheet can be found at: Micro-drives M2232U-24-GS-050.

    The rectifier can be dynamically configured for 3-phase or single phase operation with or without bulk capacitors of 1µF and 10µF.
