Narrative:

Departure from bmg airport communicating with hulman departure. Cleared to 10000 ft. As I passed through 6000 ft, the #1 inverter quit working, disengaging the autoplt and the altitude pre select. At about the same time I was dealing with the inverter problem, one of the passenger in the rear of the aircraft was looking for more air in the rear of the aircraft before she became ill. As I selected the other inverter and handed her a sick sack from the drawer behind my seat, I passed through 10000 ft. By the time I realized this, I was at 10500 ft. Right away I lowered the nose of the aircraft and advised ATC that the tops were 10400 ft. They then told me to maintain 10000 ft and call center. At no time was there any conflicts with other traffic. If this were to happen again, I would fly the aircraft first and deal with the passenger later. As I stated, at no time was there any traffic conflicts.
