Homemade 10KV electronic load

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.
