Abstract:
The DC/DC converter has a full bridge circuit, a transformer and a rectifying unit. The full bridge circuit is connected to a source DC voltage. The transformer is connected to full bridge circuit and receives the source DC. The transformer has a stationary winding and at least one selectable winding connected in series. If the source DC voltage is lower than a threshold value, the switch is turned on to increase the coupling ratio of the transformer. Therefore, the transformer converts the source DC to a DC voltage in a required voltage level.
