摘要： A method may include receiving a discharge request to perform discharge of a capacitor (106) of an electric vehicle; closing a first switch (118) a first circuit (116) provided in parallel with a second circuit (110) of the electric vehicle; determining a voltage drop of the capacitor, based on closing the first switch (118); and closing a second switch (112) of the second circuit (110) to perform the discharge of the capacitor (106), based on the determining the voltage drop of the capacitor (106) indicating that a battery of the electric vehicle is disconnected from the capacitor (106).

摘要： A system comprises: a high voltage (HV) direct current (DC) to DC converter (HVDC) (130) including: one or more transformers (240); a bridge driver (210) connected to a primary side of the one or more transformers (240); and one or more bridge rectifiers (220) connected to a secondary side of the one or more transformers (240), the one or more bridge rectifiers (220) including one or more bridge rectifier switches; a low voltage (LV) DC to DC converter (LVDC) connected to the HVDC (130); and a boost converter (135) including: an inductor (420) connected to the one or more bridge rectifier switches; and one or more boost configuration switches operable, in combination with the one or more bridge rectifier switches, to configure the boost converter (135) into each of a bypass configuration and a boost configuration, to regulate a voltage at the LVDC.
