    摘要: There is provided a electric power conversion method of an electric power conversion apparatus comprising: charging the capacitor by transmitting the electric power from the primary circuit to the secondary circuit; and determining whether a voltage across the capacitor is equal to or greater than a predetermined value; the electric power conversion method further comprising, upon determining that the voltage across the capacitor is greater than or equal to the predetermined value, stopping to drive the primary circuit; driving the first secondary upper arm or the second secondary upper arm; and detecting whether a short-circuiting failure occurs in the first secondary lower arm or in the second secondary lower arm based on a presence or absence of change in a voltage at the secondary port in response to driving the first secondary upper arm or the second secondary upper arm.

    摘要: A power conversion apparatus includes a transformer; a primary side full bridge circuit provided on a primary side of the transformer; a first port connected to the primary side full bridge circuit; a second port connected to a center tap of the primary side of the transformer; a secondary side full bridge circuit provided on a secondary side of the transformer; a third port connected to the secondary side full bridge circuit; and a control unit configured to cause an upper arm of the secondary side full bridge circuit to operate in an active region in a case where a capacitor connected to the third port is charged with a transmitted power transmitted to the secondary side full bridge circuit via the transformer from the primary side full bridge circuit when power of the second port is stepped up and the stepped up power is output to the first port.

    摘要: Phase differences between primary-side series-connected first and second arms and secondary-side series-connected fifth and sixth arms and between primary-side series-connected third and fourth arms and secondary-side series-connected seventh and eighth arms are controlled for power being transmitted from the secondary side to the primary side. Turn-off of the fifth arm is corrected to cause an integrating result of a secondary coil current for an interval delayed by a current sensor response delay from an interval between turn-off of the first arm and turn-on of the seventh arm to approach zero, or turn-off of the seventh arm is corrected to cause an integrating result of the secondary coil current for an interval delayed by the response delay from an interval between turn-off of the third arm and turn-on of the fifth arm to approach zero.

    摘要: Assuming that a transformer has a primary to secondary winding turn ratio 1:N, VR denotes a voltage of regenerated power, VCd denotes a discharge final voltage of a first battery connected with a transformer-primary-side center tap, VCc denotes a charge final voltage of the first battery, VBd denotes a discharge final voltage of a second battery connected with a transformer-secondary-side full bridge circuit, VBc denotes a charge final voltage of the second battery and Drain denotes a lower limit of a duty ratio D of a transformer-primary-side full bridge circuit, an apparatus determines upon (VBd/N)≦VR≦(VBc/N) that the first and second batteries may be able to be charged with regenerated power and determines upon VCd≦VR≦(VCc/Dmin) that the first battery may be able to be charged with the regenerated power.
