What is a passive precharge circuit?

This design must charge a 2mF DC-Link capacitor up to the system voltage of 800V in 0.5 seconds. However, 800V EVs can carry as much as 1000V at full charge, so the components in the design must be sized accordingly. At a high level, a passive precharge circuit is a simple RC circuit that can be represented as an exponentially decaying function.
