Narrative: I departed ZZZ in VMC and climbed runway heading to approximately 600 feet AGL and turned to heading 213 and then activated my autopilot to maintain that heading and climb to 2;000 feet and level per my IFR clearance.   Shortly afterward I instantly lost my MFD [Multi-Function Display]; #2 Radio; Autopilot and Transponder and could not receive and believed I could not broadcast on my remaining number one radio.  Transponder was gone.  I was concerned for the safety of the flight and in my mind declared an emergency.  I wanted to remain in power of gliding distance from the airport if at all possible.  I did a very thorough scan for traffic and turned for the closest downwind leg for Runway XY that I had just departed. I had to cross the approach path for Runway Y to accomplish this...about 10 seconds after turning downwind I spotted a jet descending for Runway Y.  I chose to climb abruptly for 3 reasons. 1. To slow myself down.  2. To make myself more visible. 3. To create much needed separation between the two aircraft.   After I felt I had created sufficient vertical separation I slowed the plane down and configured the aircraft for landing Runway XY; ZZZ.   On short final I spotted a solid green from the Tower and went ahead and landed safely. Subsequently from speaking to the pilot of the jet I learned he was instructed to go-around and my crossing Runway Y's approach corridor in front of him impeded his ability to do so.I contacted a Tower Controller; to debrief the incident and he informed me that I should have circled on the downwind leg of Runway XY and looked for a solid green before approaching for landing. The runway was a ghost town at the time because of COVID and I had waited for nearly 15 minutes for takeoff with only one other airplane departing during that time frame.In hind sight - I had a working hand held radio on board and a perfectly running airplane but I was worried that whatever electrical problems I was having might kill my engine; so I took the most expedient course to get my airplane on the ground safely.  I had my eyes peeled for other traffic the entire time.  Other than the few moment I spent trying to trouble shoot.
