Advanced Inrush Current Management in High Voltage Applications

DESCRIPTION

This document details the specifications for functional performance in high voltage systems, focusing on inrush current events. Key parameters include an isolation voltage threshold of 0.0001 A and an over-voltage shutdown threshold at 450 VDC +/- 5%, with returning values at 430 VDC +/- 5%. The under-voltage derating threshold is set at 275 VDC +/- 5%, ensuring safety against excessive input currents (1.6 kW at 87% = 6.7 A). Additional features include short circuit protection, jump start capabilities, reversing battery efficiency, and full bridge centertap topology for energy storage management.

  4. Output Voltage Rage Line Regulation, Steady and Dynamic Steady – 5% Dynamic – 10%(5 msec max) Over-Voltage Shutdown Threshold 450VDC +/-5% Returning value 430VDC +/-5% Under-Voltage Derating Threshold 275 VDC +/- 5%. The derating should be sufficient to prevent damage to the APM from excessive input currents, (1.6 kW / (87% * 275 VDC) = 6.7A).
