Title:
H-BRIDGE CONVERTER AND POWER CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2018/179234
Kind Code:
A1
Abstract:
The H-bridge converter according to an embodiment is provided with: an HF-leg 13 having a plurality of sub-legs connected in parallel, said sub-legs each including a pair of switching devices connected in series between a DC positive voltage bus line P and a DC negative voltage bus line N; an LF-leg 15 connected in parallel with the HF-leg 13 and having a pair of switching devices connected in series between the DC positive voltage bus line P and the DC negative voltage bus line N; a plurality of AC output terminals H1-H3, L0 electrically connected to between the pairs of switching devices, respectively; and a control circuit CTR controlling the HF-leg 13 on the basis of a multiphase interleaving method in which the conducting phases of the switching devices of the sub-legs are shifted to each other and controlling the LF-leg 15 to switch the output every half cycle of an output fundamental frequency f0.
