    摘要: A direct current converter includes a full-bridge inverter, a control module, a transformer, a resonant circuit, and a rectifier module. The full-bridge inverter includes a first switching device, a second switching device, a third switching device, and a fourth switching device. The control module adjusts a duty cycle of the first switching device, the second switching device, the third switching device, or the fourth switching device to a first duty cycle. The control module further controls a working frequency of the direct current converter to be a first working frequency, where an absolute value of a difference between the first working frequency and a resonant frequency of the resonant circuit is less than or equal to a threshold.

    摘要: An annular silicon steel sheet, a circular wire motor assembly, a circular wire motor, and a powertrain. The annular silicon steel sheet includes a plurality of open slots, each open slot penetrates the silicon steel sheet in an axial direction of the silicon steel sheet, and a projection of each open slot in the axial direction of the silicon steel sheet includes a first curve segment, a second curve segment, and a third curve segment. The first curve segment and the third curve segment are oppositely arranged in a circumferential direction of the silicon steel sheet, a bending direction of the first curve segment is away from a bending direction of the third curve segment, and a bending direction of the second curve segment is away from an opening of the open slot. The open slots improve the performance of the circular wire motor and the powertrain.

    摘要: A fault isolation apparatus includes a controller and a circuit breaker. When the circuit breaker is located on a bus connected to a DC/DC conversion unit, if a voltage collected by a first voltage collection terminal is a negative value, it indicates that input or output of the DC/DC conversion unit is reversely connected. In this case, if the circuit breaker is controlled to be opened, the DC/DC conversion unit can be prevented from being connected in series to other parallel DC/DC conversion units. If a voltage collected by a first voltage collection terminal is low and a current collected by a current collection terminal is large, it indicates that the DC/DC conversion unit is short-circuited. In this case, if the circuit breaker is controlled to be opened, another component connected in series to the DC/DC conversion unit can also be prevented from backfeeding energy to the DC/DC conversion unit.
