Patent ID: 8653772

Claim:
A control device for a voltage conversion device capable of voltage conversion between a power storage device and a load device, said voltage conversion device including a first switching element and a second switching element connected in series between an electric power line and a ground line of said load device, and performing said voltage conversion by a switching operation, said switching operation including a dead time identified as a period of time during which both of said first switching element and said second switching element are at an OFF state, said control device comprising: a frequency setting unit setting a carrier frequency of said switching operation, and a drive control unit configured to control switching of said first switching element and said second switching element based on a voltage command value of said voltage conversion and said carrier frequency, said drive control unit controlling switching of said first switching element and said second switching element so as to enlarge an output allowable voltage range of said voltage conversion device restricted by said dead time, based on information related to electric power input to and output from said voltage conversion device.
