A charge and discharge control device, wherein S1 used as a switching element for pressure rising and S2 used as a switching element for pressure lowering are turned on and off alternately with a dead time provided therebetween irrespective of whether an electric motor load a powering or regenerating operation is performed, whereby a DC reactor current can be operated continuously at all times, and the discontinuous state of the DC reactor current need not be detected. L'invention concerne un dispositif de commande de charge et de décharge dans lequel des commutateurs S1, utilisé afin de faire monter la pression, et S2, utilisé afin de faire baisser la pression, sont enclenchés ou déclenchés de façon alternative, avec un temps mort entre l'enclenchement et le déclenchement, que soit réalisée ou non une opération de régénération ou d'entraînement d'un moteur électrique, un courant d'inductance CC pouvant être délivré de façon continue, l'état discontinu de ce courant ne nécessitant pas de détection.
