The bi-directional DC/DC converter with high power rate plays a key role in power storage system, while it converts DC voltage or DC current for the power storage battery, and then come to the need of DC voltage/current in applications. It illustrates the design of the system hardware and software realization based on this local controller and the host computer structure in detail, in which the local controller provides the power circuit a const voltage/current in BUCK/BOOST mode, and the host computer supplies control at system level in long-distance, including setting the bi-directional DC/DC converter's operation mode, parameters' configuration and monitoring. The outcome of the experiment proved that the system can provide the power storage converter reliable and effective control, the waveforms of the voltages and currents meets the design requirements.
