Narrative:

Was practicing instrument approaches for a training flight. Upon starting the missed approach climbout there was a surge in the electricity shown through flickering lights; low bus annunciator indications; both alternators shown as inoperative; and a right altitude circuit breaker popped. We (my students and I) started turning off unnecessary equipment since we were running on our battery only; and on the way back toward the airport we started to smell something burning. The smell increased rapidly over the next 1-2 minutes and then the student observing in the back started to see smoke coming from the cockpit area. We immediately notified ATC at this point and told them we were going to land at the closest airport.
