MULTIPHASE CONVERTER

WIPO Patent Application WO/2017/082033

A1

Provided is a configuration that makes it possible to select a voltage conversion unit for driving according to a method by which it is possible to easily suppress the operation of voltage conversion units in which the temperature increases, and, in a case where there is an increase in the device temperature, to reliably suppress the increase in the temperature of the device. When a change in the state of a multiphase conversion unit (2) causes the number of reference phases to change to a number smaller than the maximum number of phases (n) of the multiphase conversion unit (2), and when the device temperature (Td) is lower than a threshold temperature (Tt1) and a high-temperature voltage conversion unit has been specified, a control unit (3) selects the specified high-temperature voltage conversion unit as a non-drive phase, and drives voltage conversion units corresponding to the number of reference phases using a first control scheme. If the device temperature (Td) is higher than the threshold temperature (Tt1), the multiphase conversion unit (2) is driven using a second control scheme in which the output is more restricted than in the first control scheme.
