Narrative:

After landing on runway 33R at bwi, we had a primary inverter warning light come on during our taxi to the gate area. The cockpit then began to fill with electrical smoke. I turned off the primary inverter and the smoke seemed to dissipate. The captain then instructed me to declare an emergency and we continued to gate area to safely deplane the passenger.
