Original Abstract Submitted

the alternating current sweep unit outputs alternating current power from three battery strings that are y-connected. the offset voltage command vst_offset is calculated by adding the offset component v*abc_off of the string voltage obtained from the string voltage command v*abc, the amplitude vamp of the command voltage calculated using dq shaft voltage command values v*d and v*q, and the margin voltage vmrg. by determining the on-time ton of the gate signal by using the string voltage command v*abc and the offset voltage command vst_offset and performing duty control on the gate signal, it is possible to set an offset voltage corresponding to the command voltage, and thus it is possible to suppress an increase in battery loss.
