摘要： A transformer comprises an iron core, a support module, a winding unit, a potting box. The potting box includes an inner wall, an outer wall and a bottom plate and the inner wall is sleeved in the outer wall. The bottom plate is connected to a bottom portion of the inner wall and a bottom portion of the outer wall and a potting space is defined by the outer wall, the inner wall and the bottom plate. The winding unit is disposed in the potting space and a magnetic pole of the iron core penetrates through an inner side of the inner wall of the potting box. The support module is disposed between at least one end surface of the potting box and a cover of the iron core to form an insulation clearance. The support odule is close to the inner wall of the potting box.

摘要： The present disclosure discloses a power conversion system and a method for suppressing the common-mode voltage. The power conversion system comprises a grid-side converter, a motor-side converter, a bus capacitor, a first reactor, a second reactor, and a third reactor. The bus capacitor is electrically connected between the grid-side converter and the motor-side converter. The first reactor includes a first terminal and a second terminal, wherein the first terminal is electrically connected to the motor-side converter. The second reactor includes a first terminal and a second terminal, wherein the first terminal is electrically connected to the second terminal of the first reactor and the second terminal of the second reactor is electrically connected to a motor. The third reactor includes a first terminal and a second terminal, wherein the first terminal is electrically connected to a grid and the second terminal is electrically connected to the grid-side converter.
