PROBLEM TO BE SOLVED: To provide a multiphase voltage conversion device in which a function need not be completely stopped while the conversion device is protected against damage even when abnormality occurs. SOLUTION: The multiphase voltage control device is provided with voltage converters 31 to 33 which are connected in parallel between a first node N1 and a second node N2 and comprise abnormality detection devices, each detecting presence or absence of occurrence of abnormality and a controller 30 operating a plurality of voltage converters in accordance with a driving request signal. The controller 30 stops the voltage converter where abnormality is detected by the abnormality detection device. When the voltage converter without abnormality detection remains, the residual voltage converter is made to maintain an operation corresponding to the driving request signal. It is desirable that the controller 30 limits the through power of the multiphase voltage conversion device when the residual voltage converter is made to maintain the operation corresponding to the driving request signal.
