Abstract
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.
