A system and method of connecting power supplies in parallel that provides desired voltage regulation at the load and current sharing between the power supplies. The power supplies are connected in parallel at the load. Each power supply also has a sense line connected at the load. Each power supply includes means for measuring the current delivered to the load. Each supply also includes an electronically controlled variable resistive element in its respective sense line. The amount of current being supplied by each power supply to the load is measured. A controller determines if an unacceptable imbalanced current condition exists, i.e., it determines which power supply is supplying too much or too little current and the controller selectively changes the value of the appropriate variable resistive element in the sense line of that power supply in order to change the current being delivered to the load in a direction that corrects for the imbalanced condition. All such corrections are controlled so that a desired voltage regulation is maintained at the load.
