The present invention refers to a method of intrinsically biasing a dual DC/DC converter by means of an active pre-charging of the internal side of the converter prior to its connection with the batteries and a soft biasing of the batteries after the connection of the converter with the batteries. This has the advantage of having a dual DC/DC converter capable of charging isolated batteries in photovoltaic installations in a pole to ground configuration, eliminating the biasing transient that occurs when connecting the battery by means of passive resistive soft charging to the internal capacitor bus of the DC/DC converter, and also eliminating the biasing transient that occurs when starting the DC/DC converter for its normal operation.
