The invention belongs to the technical field of non-contact electric energy transfer, and relates to a non-contact near-field bidirectional energy transfer system control device and control method. The method comprises the steps that: a first driving circuit collects the voltage of an input side of a switching device unit, generates a first digital signal, converts the first digital signal into a first analog signal, and outputs the first analog signal to an either-or switching circuit; a digital signal processor generates a second digital signal, outputs the second digital signal to a second driving circuit, the second digital signal is converted into a second analog signal, and the second analog signal is output to the either-or switching circuit; and the either-or switching circuit selects to connect a branch circuit according to a third digital signal generated by the digital signal processor, and outputs the first analog signal or the second analog signal to the switching device unit to control the on or
