Abstract
The present invention relates to a power conversion device, comprising: at least one resonant circuit comprising at least one resonant inductor and at least one resonant capacitor; a first transformer comprising a first primary winding which is electrically connected to the resonant circuit and at least one first secondary winding; and a second transformer comprising a second primary winding which is electrically connected to the resonant circuit and at least one second secondary winding, the second primary winding and the first primary winding are connected in parallel and have the same number of coil turns, and the second secondary winding and the first secondary winding have the same number of coil turns; an deviation of inductance between the first primary winding and the second primary winding meets |Lm1−Lm2|/(Lm1+Lm2)<=30%, Lm1 is the inductance of the first primary winding, and Lm2 is the inductance of the second primary winding.
