Aircraft
The takeoff was uneventful and our clearance assigned an altitude of 3;000 feet. We were turned over to TRACON where we were given a clearance to climb to 9;000 feet. After entering the overcast at about 3;500 feet and climbing we received an AOA deice Caution and Warning System (CAWS). At about 6;000; and in IMC; I felt that given the forecast icing along our route; it necessary to return to [departure airport]. We told ATC that we wanted to return for a maintenance issue. We were asked if we were [advising of an emergency situation]. Since we were not seeing any airframe ice at the time we responded no.We were given vectors and a descent and during that maneuvering in IMC we noted an avionics buss CAWS and a non-essential buss CAWS with both Electronic Attitude Direction Indicator and Electronic Horizontal Situation Indicators on both the Pilot in Command and Second in Command panels going blank. I transitioned to the peanut gyro and Radio Magnetic Indicator for maneuvering and [advised ATC].We re-entered VMC at about 3;500 feet and had visual contact with [departure airport]. We landed without further event.
