APPENDIX D
Resistive Regeneration Sizing
Shunt regeneration is required to dissipate energy that is pumped back into the
DC bus during load deceleration. The loads need to be defined in terms of
system inertia, maximum speed, and deceleration time. In addition, the duty
cycle must be known.
The black wires are for the thermostat and the white wires are for
the regen resistor on the external regen resistor (pictured above).
