ABSTRACT:
A device for controlling a plurality of parallel connected converters which includes a reference circuit for controlling the converters, a frequency divider having a number of outputs corresponding to a number of the converters, and a plurality of ring counter circuits for driving the converters in response to the output of the frequency divider. Interlocking signals are supplied among the ring counter circuits such that the ring counter circuits recover when a noise signal is applied.
