Auto-synchronous isolated inlet power converter
First Claim
1. An auto-synchronous isolated inlet power converter, comprising:
- a direct current (DC) source configured to supply DC power;
an alternating current (AC) inlet receptacle configured to receive external input AC power generated from an AC power source external to the auto-synchronous isolated inlet power converter;
an AC outlet receptacle configured to provide output AC power to systems external to the auto-synchronous isolated inlet power converter;
a DC to AC converter configuration configured to;
generate paralleled output AC power to the AC outlet receptacle when the auto-synchronous isolated inlet power converter is operating in a slave mode, wherein the paralleled output AC power is the output AC power generated from the external input AC power and the DC power supplied by the DC source that is converted to additional AC power that is synchronized and in parallel with the external input AC power, andgenerate the output AC power to the AC outlet receptacle when the auto-synchronous isolated inlet power converter is operating in a master mode, wherein the output AC power is generated from the additional AC power converted from the DC power supplied by the DC source and is not in parallel with the external input AC power.

Abstract
An auto-synchronous isolated inlet power converter is disclosed that can be daisy-chained with other power converters and/or an alternating current (AC) power source. The power converter automatically generates output AC power that is in parallel with external input AC power coming into the power converter when the power converter senses the external input AC power so that the power converter operates as a slave in this state. The power converter automatically generates output AC power when the power converter fails to detect the external input AC power coming into the power converter where the power converter operates as a master in this state. The power converter generates the output AC power without any reliance on the external input AC power generated by a utility grid and/or other AC power sources external to the power converter.

8. A auto-synchronous isolated inlet power converter configuration, comprising:
-
a first auto-synchronous isolated inlet power converter included in a plurality of auto-synchronous isolated inlet power converters configured to; automatically generate first output alternating current (AC) power for the first auto-synchronous isolated inlet power converter when the first auto-synchronous isolated inlet power converter fails to detect first external input AC power coupled to the first auto-synchronous isolated inlet power converter, wherein the first output AC power is output AC power generated from DC power of the first auto-synchronous isolated inlet power converter and is not in parallel with the first external input AC power, and act as a master auto-synchronous isolated inlet power converter when the first auto-synchronous isolated inlet power converter fails to detect the first external input AC power coupled to the first auto-synchronous isolated inlet power converter, wherein the master auto-synchronous isolated inlet power converter automatically provides the first output AC power to a slave auto-synchronous isolated inlet power converter included in the plurality of auto-synchronous isolated inlet power converters; and a second auto-synchronous isolated inlet power converter included in the plurality of auto-synchronous isolated inlet power converters configured to; automatically transition into generating second paralleled output AC power, wherein the second paralleled output AC power is second output AC power generated by the second auto-synchronous isolated inlet power converter that is in parallel with the first output AC power generated by the first auto-synchronous isolated inlet power converter, and act as the slave auto-synchronous isolated inlet power converter when the second auto-synchronous isolated inlet power converter detects the first output AC power provided by the first auto-synchronous isolated inlet power converter. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
