The invention discloses a multipath bidirectional voltage transformation control device and a controller, the device comprises a state detection module, an LLC bidirectional control module, a boost module and a buck module, and the state detection module is used for detecting a working state; the LLC bidirectional control module is used for performing forward voltage conversion control on the LLC bidirectional transformation circuit so as to convert the first direct current into second direct current and charge the charge-discharge battery; or second direct current output by charging of the charging and discharging battery is converted into the first direct current; the boost module is used for performing voltage boost conversion on the boost circuit so as to convert the third direct current into the second direct current and charge the charge-discharge battery; the buck voltage reduction module controls the buck voltage reduction circuit and converts the second direct current output by the charging and discharging battery into fourth direct current. Management and control of each charging and discharging loop are realized through each module in the multipath bidirectional voltage transformation control device, the overall circuit coordination is relatively good, and the overall circuit failure rate is relatively low.
Description
technical field [0001] The present invention relates to the technical field of power supply, in particular to a multi-channel bidirectional voltage transformation control device and a controller. Background technique [0002] Existing mobile energy storage devices, such as mobile inverters, can output power from lithium batteries to provide power for electrical equipment. Charge. Among them, the conversion of the DC power supply voltage for charging and discharging and the inversion of the voltage are the key circuits of the mobile energy storage device. [0003] When this type of electronic equipment is used outdoors, it usually needs to meet the input and output of multiple voltages, for example, outputting low-voltage direct current to supply power to electronic equipment, or outputting alternating current of mains to supply power to electrical equipment. When charging, it also needs to support multiple charging methods. For example, charging by alternating current, or...
