The invention discloses a vehicle-mounted bidirectional charger. The vehicle-mounted bidirectional charger mainly solves the problems that a battery of an existing vehicle-mounted bidirectional charger is low in utilization rate, and frequency fluctuation of a power grid is caused when the existing charger is connected into or disconnected from the power grid. The vehicle-mounted bidirectional charger comprises a single chip microcomputer control circuit, and further comprises a power switching circuit and a charging circuit which are connected with the single chip microcomputer control circuit, and a high frequency invert circuit which is connected with the charging circuit, wherein the power switching circuit is further connected with the charging circuit. By adopting the design, the vehicle-mounted bidirectional charger can effectively optimize the circuit structure by using a driving circuit to replace a hardware circuit on the premise of guaranteeing efficiency, and reduces loss of devices, thereby reducing cost. By arranging the power switching circuit meanwhile, the vehicle-mounted bidirectional charger is stable in the power grid charging and load power supply switching process, and reduces the frequency fluctuation of the power grid. Accordingly, the vehicle-mounted bidirectional charger has high use value and promotion value.
Description
technical field [0001] The invention relates to the technical field of chargers, in particular to a vehicle-mounted bidirectional charger. Background technique [0002] Electric vehicle (Electronic Vehicle, EV), as a representative of new terms such as energy saving, innovation, and environmental protection, has quickly entered everyone's field of vision and achieved rapid development. As the core component of electric vehicles, the charger's structural design and performance improvement have become a hot topic of research. [0003] According to the different installation positions, it can be divided into two categories: vehicle-mounted and non-vehicle-mounted. Vehicle-mounted charger refers to the charger fixedly installed on the electric vehicle, which has the advantages of small scale, fast heat dissipation, light weight, etc., and most of them are used in conventional charging. The on-board charger is mainly used for two-way energy exchange between electric vehicles an...
