Abstract:
A direct current to direct current (DC-DC) converter includes a k-th order converter including a reactor, multiple semiconductor switching elements, and multiple capacitors respectively connected in parallel with the semiconductor switching elements (k is a natural number equal to or below N and N is a natural number equal to or above 3), a transformer having a primary winding through an N-th order winding, and a controller that controls switching of a primary converter through an N-th order converter.

Claim (Index 1):
A direct current to direct current (DC-DC) converter comprising:\n a k-th order converter including a reactor, a plurality of semiconductor switching elements, and a plurality of capacitors respectively connected in parallel with the semiconductor switching elements (k is a natural number equal to or below N and N is a natural number equal to or above 3); a transformer having a primary winding through an N-th order winding; and a controller that controls switching of a primary converter through an N-th order converter, wherein the reactor of the k-th order converter is the reactor connected to the k-th order winding and/or a leakage inductance of the k-th order winding, wherein each of the primary converter through the N-th order converter includes a full bridge circuit, wherein when the controller performs first control with each of the primary converter through the N-th order converter set to be an input converter or an output converter, the controller controls a switching operation such that the semiconductor switching element located in an upper side of a first arm of the input converter matches the semiconductor switching element located in an lower side of a second arm of the input converter in terms of an on period, controls a switching operation such that the semiconductor switching element located in a lower side of the first arm of the input converter matches the semiconductor switching element located in an upper side of the second arm of the input converter in terms of the on period, does not control a switching operation on two semiconductor switching elements located in the upper sides or the lower sides of the first arm and the second arm of the output converter, controls a switching operation with a phase difference of about 180 degrees on other two secondary semiconductor switching elements on a secondary side located in the upper sides or the lower sides of the first arm and the second arm of the output converter, controls a switching operation such that one of the other two secondary semiconductor switching elements on the secondary side located in the upper sides or the lower sides of the first arm and the second arm matches each of the semiconductor switching element located in the upper side of the first arm of the input converter and the semiconductor switching element located in the lower side of the second arm of the input converter in terms of the on period, and adjusts output power of the output converter by varying an on-duty of each of the switching operations.
