POWER CONTROL SYSTEMS AND METHODS
First Claim
1. A power supply configured to be operatively connected to at least one load, comprising:
- an AC bus operatively connected to the load;
a first AC power source operatively connected to the AC bus;
a DC bus;
a DC/AC converter operatively connected between the DC bus and the AC bus;
a first DC power source; and
a load balancer operatively connected between the first DC power source and the DC bus;
whereinthe power supply operates ina first mode in which power is supplied to the load from the first AC power source through the AC bus; and
a second mode in which power is supplied to the load from the first DC power source through the DC bus, the DC/AC converter, and the AC bus.

Abstract
A power supply configured to be operatively connected to at least one load, comprising an AC bus operatively connected to the load, a first AC power source operatively connected to the AC bus, a DC bus, a DC/AC converter operatively connected between the DC bus and the AC bus, a first DC power source, and a load balancer operatively connected between the first DC power source and the DC bus. The power supply operates in a first mode in which power is supplied to the load from the first AC power source through the AC bus and in a second mode in which power is supplied to the load from the first DC power source through the DC bus, the DC/AC converter, and the AC bus.

15. A power control system to operatively connect at least first and second AC power sources and at least first and second DC power sources to at least one load, comprising:
-
an AC bus operatively connected to the load; a DC bus; a DC/AC converter operatively connected between the DC bus and the AC bus; a first DC/DC converter operatively connected between the first DC source and the DC bus; a second DC/DC converter operatively connected between the second DC power source and the DC bus; a load balancer operatively connected to at least one of the first and second DC/DC converters; a first control switch operatively connected between the DC/AC converter and the AC bus; a second control switch operatively connected between the first AC power source and the AC bus; and a third control switch operatively connected between the second AC power source and the AC bus.

- 16. A power control system as recited in claim 16, in which the load balancer substantially equalizes the charge on first and second split rail capacitors.
-
20. A method of supplying power to at least one load, comprising:
-
operatively connecting an AC bus to the load; operatively connecting a first AC power source to the AC bus; providing a DC/AC converter to convert voltages between the DC bus and the AC bus; operatively connecting a load balancer between a first DC power source and the DC bus; and operating the power supply in a first mode in which power is supplied to the load from the first AC power source through the AC bus; and a second mode in which power is supplied to the load from the first DC power source through the DC bus, the DC/AC converter, and the AC bus.
