ABSTRACT:
A thermally regulated power system, where the extent to which the temperature of a power module causes a change in the output power of the module depends on the output current of the module. Similarly, the extent to which the output current of the power module causes a change in the output power of the module depends on the temperature of the module. In one embodiment, a thermally regulated down slope power sharing system without a share line includes N+1 power modules coupled in parallel to the same output port, where N is an integer greater than one. The slope of the down slope curve of a power module is changed in response to the temperature of the power module such that a power module operating at a higher temperature outputs less current for a given bus voltage than a power module operating at a lower temperature. In another embodiment, the power system includes 2N power modules, where one group of N power modules is coupled to each other by a first share line and another group of N power modules is coupled to each other by a second share line. This allows the power output of the power modules to be controlled by thermally regulated down slope sharing and by temperature/current share lines.
