Abstract
A device includes an alternating current (AC) to direct current (DC) converter configured to convert a single-phase AC power signal to a DC power signal. The device may also include a DC to AC converter having an input electrically coupled to the AC to DC converter and configured to receive the DC power signal and having and one or more inverters coupled to the input and configured to change the DC power signal to a multi-phase power supply having at least four AC power signals that are phase-shifted relative to each other.
Claims20
A device comprising:
- an alternating current (AC) to direct current (DC) converter configured to convert a single-phase AC power signal to a DC power signal;
- and
- a DC to AC converter comprising:
- an input electrically coupled to the AC to DC converter and configured to receive the DC power signal;
- and
- one or more inverters coupled to the input and configured to change the DC power signal to a multi-phase power supply having at least four AC power signals that are phase-shifted relative to each other.

A method comprising:
- electrically coupling an alternating current (AC) to direct current (DC) converter to a DC to AC converter, wherein the AC to DC converter is configured to convert a single-phase AC power signal to a DC power signal;
- and
- electrically coupling an output of the AC to DC converter to one or more inverters that are configured to change the DC power signal to a multi-phase power supply having at least four AC power signals that are phase-shifted relative to each other.
A method comprising:
- converting a single-phase alternating current (AC) power signal to a direct current (DC) power signal;
- and
- converting the DC power signal to a multi-phase power supply having at least four AC power signals that are phase-shifted relative to each other.
