Control device for converter and electrically powered vehicle provided with the same

A control device for a converter, said converter being provided between a DC power supply and an electrical load device and boosting an output voltage to be not less than a voltage of said DC power supply,

• said converter comprising:
• a reactor having one end connected to a positive electrode of said DC power supply;
• a first switching element connected between the other end of said reactor and said electrical load device;
• a second switching element connected between the other end of said reactor and a negative electrode of said DC power supply;
• and
• first and second diodes connected in anti-parallel to said first and second switching elements, respectively,
• an operation of said first and second switching elements including a dead time for preventing said first and second switching elements from being simultaneously brought into conduction, and
• said control device comprising:
• a voltage control unit performing a control operation for adjusting said output voltage to a target voltage;
• a current control unit performing a control operation for adjusting a current flowing through said reactor to a target current, using a control output of said voltage control unit as said target current;
• and
• a signal generation unit generating a signal for driving said first and second switching elements based on the control output of said current control unit.
