Abstract
A plurality of current controlled converters coupled in parallel are controlled by a central regulation circuit. Each individual converter includes an auxiliary regulation circuit which is coupled to provide backup regulation if the central regulation circuit fails. The auxiliary regulation circuit has high and low response limits which come into action depending upon whether the central regulation fails in a high or low mode. This permits the converter to remain operative and continue to regulate its output within a predefined backup limit when the central regulation circuit fails.
