| 摘要 | A power converter includes a power converter section (4) (e.g., an inverter circuit) having a plurality of switching elements (Sp, Sn) in which a current can flow in a reverse direction, and a control section (10) which determines on-state time of each of the switching elements (Sp, Sn) according to an output voltage of the power converter section (4), thereby switching on/off states of the switching elements (Sp, Sn). The control section (10) instructs the power converter section (4) to perform synchronous rectification, and corrects the on-state time according to a drop of an on-state voltage of each of the switching elements (Sp, Sn). | ||

| 主权项 | 1. A power converter comprising: a power converter section (4) having a plurality of switching elements (Sp, Sn) in which a current can flow in a reverse direction, and a control section (10) which determines on-state time of each of the switching elements (Sp, Sn) according to an output voltage of the power converter section (4), thereby switching on/off states of the switching elements (Sp, Sn), wherein the control section (10) instructs the power converter section (4) to perform synchronous rectification so that a predetermined one or more of the switching elements (Sp, Sn) is turned on, to make a current flowing through the predetermined one or more of the switching elements (Sp, Sn) flow in the reverse direction, and corrects the on-state time according to a drop of an on-state voltage of only the switching elements (Sp, Sn). | ||
