Abstract
A generator system can include a generator configured to output an alternating current (AC) generator output, a rectifier operatively connected to the generator and configured convert the AC generator output into a direct current (DC) rectifier output, and a four wire inverter operatively connected to the rectifier to receive the DC rectifier output, the four wire inverter configured to convert the DC rectifier output into 3 phase AC inverter output, wherein the four wire inverter can include three output wires, each output wire configured to output a respective phase of the 3 phase AC, wherein the four wire inverter can include a fourth neutral wire for providing a neutral path.
Claims9
A generator system, comprising:
- a generator configured to output an alternating current (AC) generator output;
- a rectifier operatively connected to the generator and configured convert the AC generator output into a direct current (DC) rectifier output;
- and
- a four wire inverter operatively connected to the rectifier to receive the DC rectifier output, the four wire inverter configured to convert the DC rectifier output into 3 phase AC inverter output, wherein the four wire inverter includes three output wires, each output wire configured to output a respective phase of the 3 phase AC, wherein the four wire inverter includes a fourth neutral wire for providing a neutral path, wherein the system includes one or more filters in electrical communication with the inverter, wherein the one or more filters include at least one of a common mode filter or a differential mode filter, wherein the common mode filter is disposed upstream of the inverter, wherein the common mode filter is disposed between the rectifier and the inverter.
