<p>A current detector (12) detects current flowing through the same wire components of a plurality of chopper devices (100A, 100B) connected in parallel. A current waveform processing unit (13) processes the detected current waveform and generates a current deviation signal (DeltaI) representing the current deviation between the chopper devices (100A, 100B). Based on the current deviation signal (DeltaI), a switching signal correction unit (22) corrects switching signals (Sa٭, Sb٭) generated by a switching signal generation unit (21) so that the current deviation between the chopper devices (100A, 100B) reduces.</p> |
