Abstract
A phase adaptable AC/DC converter having three input terminals capable of connection to either a single phase or dual phase electrical power service. A feedback circuit in a control portion of the converter sums a first voltage and a second voltage which are proportional to first and second output voltages, respectively, to control a first bidirectional switch in a voltage boost circuit. The feedback circuit also sums the first and second voltage with a difference between the first and second output voltages to control a second bidirectional switch in the voltage boost circuit.
