A power and control architecture employing circuitry that sequentially regulate power flows from independent solar-array sources or a mixture of power sources providing power to a common load. The device may be used on a satellite with solar-array sources; however it may also be used on ground based systems. Stiff bus voltage regulation is obtained by tightly controlling the most recently activated power-processing channel while keeping the previously activated power-processing channels in the Maximum Power Tracking mode to supply maximum power to a common load. The remaining power-processing channels are turned off or operated in stand-by mode. In an alternative system, with primary design goal of uniform power sharing among solar-array sources, all solar array sources are activated with uniform power sharing at light load and, as load demand increases, sequentially controlled to operate in the Maximum Power Tracking mode one solar array source at a time as necessary.

In an aircraft galley, a power network distributes power from a source to electrical consuming devices (oven, water boiler, coffee machine, trash compactor, etc.). A control unit is connected to and can individually address each of the devices via a databus. The control unit compares the actual existing power consumption to a prescribed maximum value. If the actual consumption reaches the maximum value, the control unit calls up a power reduction procedure from a catalog in a database, and provides corresponding control signals to one or more of the devices to reduce the power consumption below the maximum value. The individual devices receive power in a time-sharing, power-sharing, or time-staggered manner. An intelligent distribution of available power resources avoids power overloads, and allows optimal utilization of all galley devices without limiting the normal catering process.

A combination oven includes convection, steam and microwave cooking sources. When implementing a user selected cooking program using the microwave source and at least one of the other sources, the oven control is configured to implement the cooking program in a manner using an input food product mass value to set microwave energy level applied to the food product during operation of the cooking program and without changing cook time as set by the cooking program. The microwave energy level may be set such that end product achieved without changing cook time has a comparable degree of doneness regardless of mass. The oven control, or a separate computerized device, may be used to automatically convert a non-microwave cooking program into a microwave enhanced cooking program that is stored by the oven control for selection by an operator. Where a collective power consumption capability of the convection heat cooking source, steam cooking source and microwave energy cooking source is higher than rated power available from a power source of the combination oven, the oven control implements power sharing rules.

A power sharing process for base station to allocate un-utilized power from a 1× system to an EVDV system is shown. In this process, a power sharing module receives input signals that relate to predicted power allocation for the 1× system and current power allocations for the 1× system and the EVDV system.
