发明名称 Ground fault detection circuit for use in high voltage motor drive applications
摘要 An integrated ground fault detection circuit in accordance with an embodiment of the present application includes a shunt resistor provided on a positive rail of a DC bus, a high voltage pocket including a sensory circuit connected to the shunt resistor and operable to detect a fault condition indicating a short circuit and a transmitter section operable to continuously transmit a fault condition signal indicating the fault condition and a low voltage pocket including a receiver operable to receive the fault condition signal from the sensory circuit and a logic unit, connected to the receiver, and operable to provide a fault output signal indicating the presence of a fault condition based on the fault condition signal.
