    • AC reactor Nidec Leroy-Somer has made the technological choice to install an AC input reactor upstream of the rectifier in order to limit the disturbances described above. The recommended inductances are outlined in §2.5.1.2. They comply with EN 50178, EN/IEC 61558-2-20, EN/IEC 60076-6.

  • Page 12: Rectifiers

    GENERAL INFORMATION 1.2.2 - Rectifiers POWERDRIVE MD Smart rectifiers are elements offered on an IP00 chassis. They generate a DC voltage from the voltage of the three-phase AC power supply network that supplies them. They are AC/DC converters. The offer includes 2 types of rectifiers: - Passive rectifier: used with basic power supplies (three-phase network), operating in 2 quadrants.
  • Page 13 GENERAL INFORMATION Different drive configurations make it possible to respond to this problem of reinjection of harmonics into the network. Indeed, depending on the choice of the drive architecture and/or adding filters (active or passive), the level of harmonics is reduced. The choice of configuration is related to the required harmonic distortion rate (THD, rate expressed in percentage).

  • Page 14: Active Rectifiers

    GENERAL INFORMATION The Nidec Leroy-Somer offer consists of: Single rectifier chassis The MD3REC1 single rectifier chassis is a mixed three-phase bridge assembly: 3 thyristors and 3 switching diodes. The 3 thyristors are only used to preload the DC BUS at start-up. After this phase, the rectifier is used as a full voltage diode bridge.
  • Page 15 GENERAL INFORMATION Absorbed line current, MDR THDI (*) <5% The active rectifier is incorporated into an MD3INV inverter chassis. Since the DC output of an active rectifier consists of a high value of capacitors, it is imperative, when powering on, to gradually raise the voltage of the DC bus before unlocking the rectifier.

  • Page 16: Preload Module

    GENERAL INFORMATION MD3INV chassis are available in 3 sizes depending on the desired power level. MD3INV Size 1 Size 2 Size 3 Up to 200 kW single module chassis 250 kW to 315 kW 400 kW to 500 kW tri-module chassis tri-module chassis Beyond 500 kW, the MD3INV chassis can be combined in parallel up to 5 per output, allowing a power output of 2.5 MW.

  • Page 17: Parallelisation Module

    GENERAL INFORMATION 1.2.5 - Parallelisation module Above 500 kW, the rectifier and inverter chassis shall be installed in parallel to achieve the required power levels (up to 2.5 MW). In this configuration, the first inverter (or active rectifier) chassis must be associated with a control module and each additional chassis must be associated with an MD3PRL parallelisation module.

  • Page 26: Liquid Cooling (Cl Version)

    GENERAL INFORMATION 1.4.2 - Liquid cooling (CL version) When the environment is incompatible with air cooling, or when there is a congestion or noise constraint, the use of a liquid cooled variable speed drive provides a compact and waterproof solution. In this version, all Powerdrive MD Smart power modules are mounted on a cold plate (CL version) on which the heat sinks are attached.

  • Page 27: Internal Loss Management

    GENERAL INFORMATION 1.4.3 - Internal loss management Losses generated inside the enclosure are from power and passive components. In order to evacuate them several methods are possible: • Extractors and filters: when the room temperature is always below the required enclosure temperature and the enclosure is in a low-pollution environment, fans are the easiest and most efficient solution.

    TESTING 5.2.2 - Test preparation 1) Wire the 400 Vac three-phase network to terminals L1, L2, L3 and wire the ground to the equipotential protection bar 2) Wire the motor to the U, V, W terminals (in sequence) 3) Wire the button box on the corresponding terminal blocks (see section §4.11) and ensure that the "STO-1 and STO-2" inputs are opened (variable speed drive lockout) 5.2.3 - Functional Testing 1) Perform the following test set-up:...
  • Page 156 TESTING 10) Put the oscilloscope clamp on a network phase and check the waveform. Check the waveform below for other network phases. Sample waveform for an MD3REC rectifier 11) Load the motor at the variable speed drive’s rated intensity and check that the level of imbalance of the network currents is less than 8%.
