  • Patent number: 7615979
    Abstract: Flexible power converter and simplified process controller capable of being configured for a variety of applications with minimal effort. The power converter has a plurality of power switches that can be configured for multiple topologies through selectable routing of switch commands. The process controller can be adjusted through a single timing parameter to process the configured feedback signal. External settings or serial port configuration enable stand-alone or processor-based operation. The invention may be quickly and easily applied as a versatile power supply, motor driver, thermal regulator, or controller for lighting and flow applications. The flexible power converter and simplified process controller reduces development time and cost, reduces parts count and cost, and improves performance and reliability of power and control systems.
