Abstract
A bi-directional high voltage DC-DC converter capable of detecting and avoiding a bypass and an operating method thereof, by detecting whether a bypass has occurred and performing an operation for avoiding the bypass and/or an operation for coping with the bypass when the occurrence of the bypass is detected, can detect the occurrence of the bypass to avoid system defects, and detect the occurrence of the bypass in an existing system without adding a voltage sensor and a current sensor.
Claims20
A bi-directional high voltage DC-DC converter to be connected to a fuel cell control unit installed in a fuel cell electric vehicle, the bi-directional high voltage DC-DC converter comprising:
- a control circuit configured to detect whether a bypass in the bi-directional high voltage DC-DC converter has occurred, based on an input voltage and an output voltage of the bi-directional high voltage DC-DC converter;
- and
- a conversion circuit configured to convert a voltage according to control of the control circuit.
A method of operating a bi-directional high voltage DC-DC converter connected to a fuel cell control unit installed in a fuel cell electric vehicle, the method comprising:
- obtaining an input voltage and an output voltage of the bi-directional high voltage DC-DC converter;
- and
- detecting, based on the input voltage and the output voltage of the bi-directional high voltage DC-DC converter, whether a bypass in the bi-directional high voltage DC-DC converter has occurred.
