Abstract
The present invention relates to a single phase, non-insulated, miniaturized DC/AC power inverter (1) having an output power density higher than 3000 W/dm3, wherein said first (S1_H), second (S1_L), third (S2_H) and fourth (S2_L) switches are made of wide-band semiconductors and preferably of gallium nitride or GaN semiconductors; and wherein said DC/AC power inverter (1) further comprises: a ripple-compensating active filter comprising a third half-bridge (203) having a fifth switch (S3_H) in series with a sixth switch (S3_L), said fifth switch (S3_H) being connected at one end to the positive terminal (L+) of the DC input, said sixth switch (S3_L) being connected at one end to the negative terminal (L−) of the DC input,the other end of the fifth switch (S3_H) being connected to the other end of the sixth switch (S3_L), defining a third common end, said third common end being connected to a first end of a LC filter, made of at least one inductor (L6) and one storage capacitor (C5), a second end of the LC filter being connected to the negative terminal (L−); modulation control means of said first (S1_H), second (S1_L), third (S2_H), fourth (S2_L), fifth (S3_H) and sixth (S3_L) swit…
