“…Generally, the battery is charged with a single converter [26]. However, when charging a battery with large-capacity, charging may be performed by parallel operation of multiple converters, and in that case, it is common to use a balance circuit that controls the charging output balance between the respective parallel-connected converters.…”

The control of CO 2 emission is a global urgent issue, and the decarbonizing is being promoted in various fields. Also at residences, the electricity consumption is increasing instead of fossil fuels because of the electrification of heat source, shifting from gasoline car to EV and so on, therefore the reduction of the increasing burden of commercial power generation caused by the increase of electricity consumption at residence is extremely important task. Distributed power systems for households that can supply necessary electricity by renewable energy to each house is considered to be an effective solution. In order that the distributed power system which is desirable to be able to use various renewable energy become widely used for households, independent and autonomous operation of each power source is an important factor. This paper presents the behaviour of the power control in parallel operation of dc-dc converters directly connected to the dc bus with battery and the power behaviour of whole system. As a result, it was found that when multiple conditioners are connected to the dc bus in a renewable energy system for household, it is possible to realize autonomous charging with good balance even without the current balance control. It is important to expand use of the combination of dc bus and autonomous converters to utilize various renewable energy sources in the EV society coming in the near future.
