POWER CONVERSION MODE CONTROL APPARATUS AND METHOD OF BI-DIRECTIONAL DC-DC CONVERTER AND BI-DIRECTIONAL DC-DC CONVERTING APPARATUS INCLUDING POWER CONVERSION MODE CONTROL APPARATUS

摘要

There are provided a power conversion mode control apparatus of a bi-directional DC-DC converter including: a controlling unit determining an overall reference current so as to perform a power conversion from a side in which an actual voltage is relatively larger than a reference voltage to a side in which the actual voltage is relatively smaller than the reference voltage by comparing a voltage error of low voltage side and a voltage error of high voltage side with each other; and a duty command generating unit generating duty command based on a difference between the overall reference current and a current of low voltage side and providing the duty command to the bi-directional DC-DC converter.
