<p><P>PROBLEM TO BE SOLVED: To provide a converter controller more correctly detecting a reactor current irrespective of a difference in response delay between current sensors for detecting a reactor current. <P>SOLUTION: A reactor current detecting means 230 detects reactor currents at the time points of valley and crest of a triangular wave supplied from an oscillation means 210 (i.e., points of the maximum changes of the triangular wave), and outputs the detected currents to an average reactor current deriving means 240. The average reactor current deriving means 240 averages pairs of reactor currents Ida to be detected at the time point of the valley of the triangular wave and reactor currents Imo detected at the time point of the crest of the triangular wave (reactor current Ida-1 and reactor current Imo-1) supplied from the reactor current detecting means 230, thereby deriving average reactor currents Iave-1 to Iave-k. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
