Nidec asi silcovert h series Presentation Transcript

  • 1. SILCOVERT H Series PPT2013.01.01.14EN www.nidec-asi.com
  • 2. Silcovert H Series Silcovert H Series are a Multi Level Converters with LV IGBT power devices and a more efficient and precise control for induction and synchronous motors. PPT2013.01.01.14EN www.nidec-asi.com 2
  • 3. Silcovert H Series Our H-series drives are compatible with your existing motor systems, regardless of brand or age. Part of our analysis will address the alternative of installing a completely new variable speed drive system versus that of adding a variable frequency converter to an existing fixed speed motor or reusable equipment refurbishing. Our goal is to bring new life to your plant through the analysis of existing motors. PPT2013.01.01.14EN www.nidec-asi.com 3
  • 4. Silcovert H Series VCF Main Assemblies The variable frequency converter consists of several standard assemblies: converter, inverter, d.c. link, cooling system, controller cooling system from input transformer  ~ d.c. link =  to a.c. motor = ~ converter inverter controller PPT2013.01.01.14EN www.nidec-asi.com 4
  • 5. Silcovert H Series VCF Main Assemblies Converter: change of a.c. power with fixed frequency into d.c. power Inverter: change of d.c. power into a.c. power with variable voltage and frequency D.C. link: energy storage Cooling system: removal of the heat Controller: control of the motor, monitor and protection of the system cooling system from input transformer  ~ d.c. link = =  to a.c. motor ~ converter inverter controller PPT2013.01.01.14EN www.nidec-asi.com 5

  • 13. Silcovert NH Silcovert NH - The PWM (for USA Market and special Applications) technique with high switching frequency allows an almost sinusoidal motor current with low total losses and ripple-free torque. Its water cooling method permits to achieve high output power ranges. Power range: water cooling 2900/14400 KVA Air Cooling 1500/3700 KVA Voltage: up to 4160/6000/6600 Output Frequency: 5-140 Hz PPT2013.01.01.14EN www.nidec-asi.com 13
  • 14. Silcovert TH Silcovert TH – It’s configuration with several power cells connected in series per phase and the PWM technique with high switching frequency allows an almost sinusoidal motor current with low total losses and ripple-free torque. Its air cooling method permits to achieve an output power range up to 3000 KVA. Power range: air cooling up to 8100 KVA water cooling up to 18700 KVA Voltage: up to 4160/6000/6600/7200 V Output Frequency: 250 Hz (std) 330 Hz max with derating PPT2013.01.01.14EN www.nidec-asi.com 14
