FIELD: electricity.
SUBSTANCE: electric energy conversion device includes converter unit (20) which converts AC electric energy to DC electric energy, inverter unit (60) which converts DC electric energy to the specified AC electric energy and supplies the specified AC electric energy to electric motor (90) bringing electrically driven car into movement, casing (80) in which inverter unit (60) and its part which is grounded is arranged, and magnet core (70) which is located inside casing (80) and provides suppression of resonance current flowing between converter unit (20) and inverter unit (60).
EFFECT: effective reduction of resonance current flowing in converter unit and inverter unit in electric power conversion device for electrically driven car.
