Power Stages
OpenVVVF power stages are physical chassis/inverter assemblies that pair with the control module. Each chassis is a family of variants built around a common form factor and IGBT module choice; the same control module can drive any of them.
150 / 200 / 400 V class, per DC-link capacitor selection
465 A continuous / 600 A peak (60 s)
Implemented, under test
C2 ratings are stated in peak phase current (RMS equivalents: 330 A continuous, 424 A peak) per the IEC 61800-2 style 60 s overload convention: the 600 A peak is time-limited (60 s per event, windowed RMS over any 10 min ≤ 330 A RMS), and the 465 A continuous figure is a conservative analytical bound set by the DC-link electrolytic ripple rating at 6 kHz PWM. The DC-link plate temperature is an informational bound after the rev-B 6.35 mm spreader plate (≈ 90 °C conservative bound at the continuous point, at the FSR-08 90 °C derate onset; the model credits no convection). See OV-C2-DD-THERMAL (§6.4), OV-C2-DD-DCLINK-RIPPLE, and OV-C2-DD-DCLINK-THERMAL.
C2 current rating restated as 220 A continuous / 600 A peak (60 s, IEC 61800-2 style overload convention), replacing the previous "~600 A continuous" advertisement; continuous rating is a conservative analytical bound set by the DC-link plate temperature at 6 kHz PWM, below the ~320 A electrolytic ripple limit. References to the C2 design docs added.

C2 re-rated per OV-C2-DD-THERMAL v1.3: the 600 A figure is peak phase current (424 A RMS), and the continuous rating is raised to 465 A (330 A RMS), now set by the electrolytic ripple limit; the rev-B 6.35 mm DC-link spreader plate moved the plate temperature to an informational bound below the FSR-08 derate onset. Ratings stated in peak phase current with RMS equivalents noted.
