20090096431Optimal load controller method and device - A method and device for optimizing power output of a power generation system having a load engaging system, a load optimizing system, a load selection system, a motive driver and one or more loads or power transfer parameters. The power generation system is configured using an electrical generator to consume system power out. The load engaging system decides when and how the load or power transfer parameters are applied to and removed from the system. The load selection system enables multiple power transfer parameters to be optimized by selecting and isolating one power transfer parameter at a time to be optimized. The load optimizing system optimizes system power output by manipulating the selected power transfer parameter, dynamically in response to change in power output.04-16-2009

20090243559UNIVERSAL, FAIL-SAFE, COMMON CONTROL OF MULTIPLE ALTERNATORS ELECTRICALLY CONNECTED IN TANDEM PARALLEL FOR PRODUCING HIGH CURRENT - Two or more alternators—each typically of an economical cost and of any mixture of types and capacities—are turned by a single power source—normally the engine of a large commercial truck or bus burning fuel so as to produce minimum emissions and thus operating at such higher combustion temperature as does raises the ambient temperature of the engine compartment to 125° Celsius. The several alternators are electrically connected in tandem-parallel across a battery/load. A corresponding number of identical electronic voltage regulators, preferably of the type described in U.S. Pat. No. 5,723,972 modified according to the present invention, respectively individually control the alternators. One electronic voltage regulators externally programmed to become a designated “master” produces a “universal” control signal in response to variations in a voltage across the battery/load. This “universal” control signal is used (1) in the “master” electronic voltage regulator itself to provide regulation to an associated alternator, and is wired to all other voltage regulators externally programmed as “followers” to (2) produce in each of these voltage regulators produces a signal for the regulation control of its associated alternator not by reference to the battery/load voltage (as would be normal), but rather by reference to the “universal” control signal.10-01-2009
