Intrinsic bias method of a dual DC/DC converter. The present invention relates to a method of intrinsically polarizing a dual DC/DC converter by means of an active precharging of the internal side of the converter prior to its connection with the batteries and a gentle polarization 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 grounded configuration, eliminating the polarization transient that occurs when connecting the battery through passive resistive soft charging to the internal capacitor bus of the converter. DC/DC and also eliminating the bias transient that occurs when starting the DC/DC converter for normal operation.

La presente invención se refiere a un método de polarizar intrínsecamente un convertidor DC/DC dual mediante una precarga activa del lado interno del convertidor previamente a su conexión con las baterías y una polarización suave de las baterías posteriormente a la conexión del convertidor con las baterías. Esto tiene la ventaja de tener un convertidor DC/DC dual capaz de cargar baterías aisladas en instalaciones fotovoltaicas en configuración con polo a tierra eliminando el transitorio de polarización que se produce al conectar la batería mediante carga suave resistiva pasiva al bus interno de condensadores del convertidor DC/DC y eliminando también el transitorio de polarización que se produce al arrancar el convertidor DC/DC para su operación normal.
