PROBLEM TO BE SOLVED: To provide a controller for electric vehicle in which the resonance frequency of a DC input filter circuit is not varied even when one of two motor controllers connected in parallel is stopped and erroneous function of a signal unit is prevented while eliminating unbalance of thermal stress. SOLUTION: In a DC filter circuit located at the prestage of motor controllers 5, 6, first and second switches 1, 2 are provided at the opposite ends of capacitors 12, 22. A set of reactor unit comprises first and second reactors 11, 21 constituted such that the self inductance per single reactor at the time of additive connection, is substantially equal to two times of the self inductance when first or second reactor 11, 21 is present separately. |
