A method to improve the power factor of resistive loaded a.c. regulators is based on the association of multiple fractional power regulators sequentially turned-on using assymetrical phase-control. Load subdivision is required in order to gradually connect each fractional load in a progressive sequence to keep the power input factor between acceptable limits. Moreover, the multiple load division decreases the switched current values reducing the EMI problems. Finally, the multiple fractional power regulator topology presents a control flexibility plus an inherent redundancy which improves reliability.
