no. 1 example

[0100] Such as image 3 As shown, the power conversion apparatus 1 according to the first embodiment is connected to three voltage units 4 including a solar power source SS, a load LD, and a high-voltage battery BH.

[0101] According to the present embodiment, power conversion can be realized between three or more voltage units 4 including the load LD via the multiport transformer. For example, electric power can be supplied from the solar power source SS to both the load LD and the high voltage battery BH via the multiport transformer 3 . In addition, electric power can be supplied from the high voltage battery BH to the solar power source SS side.

[0102] The first embodiment has similar configurations and effects and advantages to those of the first reference mode. In the reference numerals used in the embodiments and the references after the first embodiment, unless otherwise specified, the same reference numerals as those used in the existing embodiments indicate the ...

no. 2 example

[0104] Such as Figure 4 As shown, the power conversion apparatus 1 according to the second embodiment is connected to three voltage units 4 including a storage battery BL, a load LD, and a high-voltage battery BH. As the secondary battery BL, it is not limited to a battery having a voltage of 12V, but batteries having other voltages may be used.

[0105] According to the present embodiment, electric power can be supplied to the load LD from both the battery BL and the high-voltage battery BH. In addition, electric power can be mutually exchanged between the battery BL and the high-voltage battery BH. Power arbitration can be performed between them. Thereafter, electric power can be supplied to the load LD from the battery BL or the high-voltage battery BH. Therefore, with the power conversion device 1, energy efficiency is likely to be improved in the entire system. In addition, this embodiment has similar configurations and advantages to those of the first reference mode...

no. 3 example

[0110] Such as Figure 6 As shown, the power conversion apparatus 1 according to the third embodiment is connected to three voltage units 4 including a DC power source DCS, a load LD, and a high-voltage battery BH. According to the third embodiment, for example, electric power can be supplied from the DC power supply DCS to both the load LD and the high-voltage battery BH via the multiport transformer 3 . In other words, while the high voltage battery BH is being charged by the DC power supply DCS, power can also be supplied from the DC power supply DCS to the load LD. Therefore, in the case where the load LD is the heater, the heater promptly performs the heating operation. In particular, the heater can be heated during charging of the high-voltage battery BH before the start of the vehicle, whereby the temperature of the catalyst and the like can be increased. In addition, this embodiment has similar configurations and advantages to those of the first embodiment.

The power conversion apparatus (1) is connected to three or more voltage units (4), includes three or more power conversion circuits (21,22,23,24,25,26,27) connected to respective units of the three or more voltage units; and a multiport transformer (3) connected to the three or more power conversion circuits at mutually different ports, inwhich at least one voltage unit of the three or more voltage units is an electrical load (LD).

Description

technical field [0001] The present disclosure relates to a power conversion device. Background technique [0002] As a power conversion device provided with first and second batteries and AC power input / output terminals, for example, Japanese Patent No. 6140602 discloses a transformer (hereinafter also referred to as multi-port Transformer) power conversion equipment. [0003] However, with the power conversion device according to the patent document as described above, the configuration of an appliance to be connected to the power conversion device is significantly limited. Therefore, it is desired to expand structural changes of devices connected to power conversion devices using multiport transformers. Contents of the invention [0004] The present disclosure has been achieved in view of the circumstances as described above, and provides a power conversion device capable of enlarging changes in configuration of appliances to be connected to the power conversion device...
