Motor Controller - What might be the purpose of these resistors?
I was looking at the video of the Tesla Model 3 motor controller(400VDC, 500A) disassembly and noticed a resistor network as in the picture below. They are 2k resistors(SMD code 202). See the picture below: ![Model 3 Inverter](https://electrical.codidact.com/uploads/XuGZxUHkhUhQWZqVPw3ywPMY) I was wondering what might be the reason for putting these resistors in a motor controller unit? Some of the reasons I have been thinking of: - Bleeding resistors for the input bulk capacitance when the controller is disconnected from the main battery - Dissipative brake when the motor is acting as a generator in order to mitigate the overvoltage on the bus. Here is the video if you are interested [video link](https://youtu.be/l6dV2re3rtM?t=10) - I've linked the part where resistors are zoomed in.
