Disclosed is a bidirectional charging system for a vehicle, which comprises: a first bridge circuit including a plurality of legs individually comprising two first switching elements which are serially connected to each other between both ends of a battery; a transformer including a plurality of first coils connected to a system or a load and a plurality of second coils which are insulated from the plurality of first coils; a motor including a plurality of input ends individually receiving a plurality of phase voltages; a plurality of conversion switches which respectively and selectively connecting each connecting node of the two first switching elements included in the plurality of legs to one of the plurality of second coils and the plurality of input ends; and a controller which controls the connecting state of the plurality of conversion switches according to a predetermined operation mode. Therefore, the minimal electric components can be used to realize power conversion.
