In one embodiment, a power conversion system includes a controller to provide power control to a converter, and a distortion mitigation circuit. In another embodiment, a system includes a converter to transfer power between a power source and a load having fluctuating power demand, and a controller to provide power control, where the controller may selectively disable the power control. In another embodiment, a power conversion system includes a controller to generate a drive signal to provide power control to a power path in response to a sense signal from the power path, where the sense signal is taken from other than the input of the power path, or the drive signal is applied to the power path at other than a first power stage.

A signal processing system may include a multiply-accumulate (MAC) unit to generate output data by performing multiply-accumulate operations on first and second input data in response to a stream of MAC instruction words, where the MAC unit is pipelined to enable it to perform a multiply-accumulate operation in response to each MAC instruction word. The system may also include an instruction generator to generate the stream of MAC instruction words by performing loop expansion on a stream of intermediate instruction words, where one intermediate instruction word may comprise a group of fields to set up the MAC unit to execute in response to the one intermediate instruction word.

Embodiments herein describe an apparatus, method, and system to track goods and services. The tracked information is provided dynamically and in real-time to an end-user of the tracking system. The tracked information can be centrally managed by a server, or can be managed in a distributed network (e.g., cloud), or by a smart device (e.g., smart-phone, tablet PC). The method comprises: storing information in a database, the information corresponding to the good or service being tracked for an end-user; determining an update to the information stored in the database; determining whether a time attribute associated with the good or service exceeds a predetermined threshold; and generating an electronic message for the end-user of the good or service in response to determining the update or when the predetermined threshold exceeds the time attribute.

A distributed energy conversion system may include one or more DC power sources and two or more inverters to convert DC power from the power sources to AC power. The AC power from the two or more inverters may be combined to provide a single AC output. A module may include one or more photovoltaic cells and two or more inverters. An integrated circuit may include power electronics to convert DC input power to AC output power and processing circuitry to control the power electronics. The AC output power may be synchronized with an AC power distribution system.

A photovoltaic system may include a first photovoltaic component having local power optimization functionality to process power at a first level, a second photovoltaic component to process power at a second level, and optimization logic to command the first photovoltaic component to accommodate system-level power optimization. The first component may be reconfigurable to accommodate the system-level optimization. The entire system may be dynamically reconfigured to continuously operate at the highest overall level of system efficiency.

A method for testing a photovoltaic (PV) module includes applying a test sequence to the integrated power converter, reversing the integrated power converter in response to the test sequence, and obtaining test results from the PV module in response to the test sequence. The test sequence may include applying reverse excitation power to output terminals of the reversible integrated power converter. The reverse excitation power may provide bootstrap power to one or more components of the integrated power converter. The test method may include activating substantially the entire reversible drive train, testing the drive train and characterizing the PV cells in the module in response to the reverse excitation power.
