Medium voltage converter
Perfect Harmony GH150
The Innomotics Perfect Harmony GH150 is the ideal drive for applications in the medium voltage range of 4 - 13.8 kV. It offers maximum flexibility with four different cooling versions and highest availability due to optional redundant cells and ultra-fast bypass switch. The Innomotics Perfect Harmony GH150 is equipped with the latest version of Inspire IQ to allow remote access to live data on site.
Benefits at a glance
- Power cell redundancy to increase reliability
Maximize your process availability thanks to an optional cell bypass and redundant cells (options for n+1 and n+2 cell redundancy available). High-speed cell bypass feature maintains a reliable and balanced output voltage without torque or speed reduction - Flexibility in cooling with 4 different cooling types
Flexible to meet any customer cooling requirements, independent of site conditions.- Direct water-cooled
- Direct air-cooled
- Indirect air-cooled (air / air heat exchanger)
- Indirect water-cooled (air / water heat exchanger)
- Remote diagnostics
The Innomotics Perfect Harmony GH150 drives will be equipped with the latest version of Inspire IQ components and have therefore access to all digital products of LDA. This includes the possibility collect remote onsite data and provide this information “live” to the control station. - Extremely motor friendly
Innomotics Perfect Harmony GH150 with its M2C topology have virtually sinusoidal voltage on the output side. The motor friendliness of the drive is perfect for retrofits and long motor cable application
- Flexibility in respect to transformer type
The transformer can be chosen according to specific requirements. In most cases the transformer is placed in an outdoor transformer bay, thus eliminating the need for active cooling and E-House space for the transformer, also reducing the fire load within the building. In most cases oil cooled (ONAN/KNAN) transformers are used. However, the transformer can also be placed indoor if required (e.g. for offshore applications). The use of dry type transformers is also possible - Separation between control and power unit possible
The control unit can be placed up to 50m away from the power section of the drive and can thus be placed in a different room which does not contain any Medium Voltage equipment.
This will allow access to the control unit also to operators that are not certified for working with medium voltage, thus allowing the customer to use his personnel more flexible. - Distributed DC-Link capacitors
Any voltage-source inverter (VSI) is equipped with the DC-Link capacitors as a temporary energy storage. With M2C topology the capacitors are distributed within the power cells and not concentrated as one large capacitor, as in 3-level or 5-level VSI drives.
Thus the fault energy is distributed and much lower for every individual capacitor. In case of a failure that affects a capacitor the effects are very local and far easier to fix - Low noise emissions
The almost sinusoidal output current of the drive is very favorable for the noise level of the attached motor
