Abstract:
Current source rectifiers (CSR) and methods for a power source including three phase lines are provided herein. The CSR includes a rectifier having a plurality of switches, each switch of the plurality of switches coupled to an associated phase line of the three phase lines. The rectifier operable to receive an alternating current (AC) input voltage and provide a direct current (DC) output voltage. The CSR also includes a controller configured to control operation of the switches in accordance with a first switching sequence when measured input voltages on at least two phase lines of the three phase lines are outside of a predetermined voltage range, and control operation of the switches in accordance with a second switching sequence when the measured input voltages on the at least two phase lines are within the predetermined voltage range.

Claim (Index 1):
A current source rectifier (CSR) system for a power source including three phase lines, said CSR system comprising:\n a rectifier operable to receive an alternating current (AC) input voltage and provide a direct current (DC) output voltage, the rectifier comprising:\n a first phase leg comprising first and second series-coupled switches coupled between a positive line and a negative line, wherein first and second diodes correspond with the first and second switches, and wherein a first node coupled to a first phase line of the three phase lines is directly connected between the first switch and a cathode end of the second diode; \n a second phase leg comprising third and fourth series-coupled switches coupled between the positive line and the negative line, wherein third and fourth diodes correspond with the third and fourth switches, and wherein a second node coupled to a second phase line of the three phase lines is directly connected between the third switch and a cathode end of the fourth diode; and \n a third phase leg comprising fifth and sixth series-coupled switches coupled between the positive line and the negative line, wherein fifth and sixth diodes correspond with the fifth and sixth switches, and wherein a third node coupled to a third phase line of the three phase lines is directly connected between the fifth switch and a cathode end of the sixth diode; and \n a controller communicatively coupled to said rectifier and operable to:\n define a predetermined voltage range in a memory of the controller by hysteresis, \n control operation of said switches in accordance with a first switching sequence when measured input voltages on at least two phase lines of the three phase lines are outside of the predetermined voltage range, and \n control operation of said switches in accordance with a second switching sequence when the measured input voltages on the at least two phase lines are within the predetermined voltage range.
