Inverter Specification

Design Rationale

Specifications

  • Input – 12-120V DC
  • Output - 12-480V AC
  • Plug-in transformer modules allow from 1 to 10 amplitude modification
  • Use turnkey, plug-in IGBT module of 2.5 kW continuous, 5 kW peak
  • Use turnkey, plug-in gate driver
  • Use pure sine wave signal generator
  • Stackable up to 10 units for up to 25kW
    • Phase cable connects units so power is in phase

Scalability and Modularity Analysis

  • Basic unit above provides up to 25kW continuous power
  • Plug in IGBT module may be scaled for higher power, up to 250 kW for a stack of 10 inverters.
  • Modular design retains allowance for different gate drivers, such as high frequency power for induction furnace power supplies and other applications
