摘要： A system for testing the existing protection schemes of a power converter. The system simulates the voltage regulator producing a voltage level below an under-voltage threshold. The system simulates the voltage regulator producing a voltage level above an over-voltage threshold. The system simulates a short in the power converter pulling down the input bus. The system simulates a short in the power converter pulling down the output bus. The system measures the system responses to these simulations against responses of a properly operating system and determines if the power converter's protection schemes are operating correctly.
