Abstract
A voltage converter for an electrified vehicle is connected between an external low-voltage source and an external high-voltage source. The voltage converter includes a power conversion device having at least two power conversion components connected in parallel. The voltage converter further includes a safety power switching device, connected to the power conversion device and comprising at least two safety power switching components, configured for providing a protection mechanism for the voltage converter in an OFF or ON selection process thereof. Also included is a safety detection controller, connected to each of the safety power switching components, configured for real-time detection of each of the safety power switching components. A real-time detecting method for the voltage converter may be used in an electrified vehicle.
