Title:
POWER CONVERTER AND POWER CONDITIONER IN WHICH SAME IS USED
Document Type and Number:
WIPO Patent Application WO/2016/067614
Kind Code:
A1
Abstract:
Provided are a power converter with which it is possible to reduce the breakdown voltage required in a capacitor, and a power conditioner in which the device is used. By controlling first through eighth switching elements (Q1-Q8) and first and second bidirectional switches (13, 14), a control unit (6) switches the state of connection between a direct-current power source (100), a first capacitor (C1), and a second capacitor (C2) with respect to a first output point (103) and a second output point (104). When the difference between the voltage (V1) of the first capacitor (C1) and the voltage (V2) of the second capacitor (C2) exceeds a prescribed threshold value, the control unit (6) controls the first through eighth switching elements (Q1-Q8) and the first and second bidirectional switches (13, 14) so that a one-side discharge mode is assumed. In the one-side discharge mode described above, only the first capacitor (C1) or the second capacitor (C2) having the higher voltage of the two is discharged.
