1. A current-type converter apparatus comprising:

  • a DC power source for supplying predetermined DC power;

    a current-type converter connected to output terminals of said DC power source, said current-type converter receiving DC power from said DC power source, performing power conversion control, and outputting the converted power;

    a load connected to output terminals of said current-type converter and supplied with output power of said current type converter; and

    a converter control unit for outputting a predetermined power conversion control signal to said current-type converter, said converter control unit controlling said current-type converter so as to cause at least two states among a powering conduction state for supplying power from said DC power source to said load within predetermined control periods of both a powering control mode and a regenerative control mode, a regenerative conduction state for regenerating power supplied from said load toward said DC power source, and a reflux state for short-circuiting the output of said current-type converter and returning the circuit current of the load, and said converter control unit varying the period length of respective states.
