Abstract:
The present invention relates to a DC/DC converter which has a full bridge configured in a switching unit and uses a half bridge, which is subordinate to the full bridge in view of circuit configuration, to automatically select such a multi-topology. More particularly, the present invention relates to a DC/DC converter using a multi-topology, which receives, in real time, feedback of an output voltage charged to a battery, operates using the half bridge when the output voltage charged to the battery is lower than a reference voltage, and operates using the full bridge when the output voltage charged to the battery is equal to or higher than the reference voltage, so as to output a wider range of voltage.

Claim (Index 1):
A DC/DC converter using multi-topology comprising: a first switching unit, composed of a 3-level half bridge, for applying a current by switching direct current input power source alternately; a second switching unit, composed of the 3-level half bridge as the same with the first switching unit in the rear of the first switching unit so as to convert to a full bridge, for applying the current by switching the direct current input power source alternately; a trans unit wherein one end is connected to the first switching unit and the other end is connected to the second switching unit, thereby applying the current, applied in accordance with switching operation of the first and second switching units, to the primary winding and then, being induced in the secondary winding to output alternating current power supply; a rectification unit for outputting an output voltage by rectifying alternating current power supply, which is outputted in the secondary winding of the trans unit, to direct current power source; and a controller for receiving, in real time, feedback of the output voltage charged to a battery, charging the battery by operating the first and second switching units using a half bridge mode when the output voltage charged to the battery is lower than a reference value, and controlling to operate the first and second switching units using a full bridge mode when the output voltage is equal to or higher than the reference value, so as to charge the battery.
