Homemade 10KV electronic load

Overview

Commercial electronic loads are more expensive, especially high-power loads such as computer power supplies that must handle transient current spikes well above their nominal ratings (1800W spike for a 600W GPU) and should be tested under worst-case conditions to Ensure stability. Most electronic loads use MOSFET-based linear designs. However, none of the published designs achieves the worst-case sustained pulse required. This design uses a series of switched high-power chassis-mounted resistors to create arbitrary loads. This approach provides extremely high scalability, low cost, and high robustness. Although the principle is simple, the sheer size and need for high-frequency switching make it a challenging design.

Questions about writing data from DSP to DATARAM in PRU1
[size=4]1.PRU adopts assembly programming, and uses C6748 to write an integer data 1234 into the DATA RAM (0x01C30000) of PRU1. PRU1 obtains the data in RAM (C3) and processes it (doubles it). After t
Please recommend a buck-boost chip
I would like to recommend a good buck-boost chip. The input is 6~24V (wide voltage input), and the output can be stable at 12V. I have seen LTC3789 used on the Internet before, but this chip does not
