P0aa6 and P0a7a

I’ve had my Prius for a while now 152k on the odometer and first about 3 weeks ago I got the p0aa6 code and I’ve been just erasing it because I have no other car and it still let me drive. This morning driving down the highway lights flicker and then car jerks a little I pull over and it won’t let me drive at most just a few feet. It only used the battery whenever the engine ran it would jerk again and throw the code again. I’m stuck on wether it’s the inverter gone bad or if it’s my transmission.
