Current-type converter apparatus
First Claim
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.

Abstract
A current-type converter including a DC power source, a current-type converter, a load and a converter control unit, the converter control unit controlling so as to cause as 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 the load toward the DC power source, and a reflux conduction state for short-circuiting the output of the current-type converter and returning the circuit current of the load, and the converter control unit varying the period length of respective states.
