摘要：
A method for testing a power bridge for an electric vehicle propulsion system, the power bridge including a switching circuit having first and second switching elements operable between "on" and "off" states. The method comprises the steps of selectively switching the first and second switching elements between the "on" and "off" states, monitoring the first and second switching elements to determine whether the first and second switching elements operate between the "on" and "off" states when selectively switched, and indicating a failure o#the switching circuit when at least one of the first and second switching elements does not operate between the "on" and "off" states when selectively switched.
