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 2):
The DC-DC converter according to  claim 1 , wherein the controller performs the first control if all the output converters are adjustable in output power through the first control, and performs second control on an output converter if the controller becomes unable to adjust the output converter in output power through the first control,\n wherein when the controller performs the second. control, the controller controls the switching operation such that the semiconductor switching element located in the upper side of the first arm of the input converter matches the semiconductor switching element located in the lower side of the second arm of the input converter in terms of the on period, controls the switching operation such that the semiconductor switching element located in the lower side of the first arm of the input converter matches the semiconductor switching element located in the upper side of the second arm of the input converter in terms of the on period, does not control the switching operation on the 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 the switching operation with a phase difference of about 180 degrees on 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 of the output converter, controls the 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 ends of the first arm and the second arm shifts in phase in terms of the on period from 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, and adjusts output power of the output converter by varying the on duty of each of the switching operations.
