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.

摘要:
A power converter may include a first power path having no energy storage and a second power path having substantial energy storage. The first and second power paths have first and second input waveforms that are complementary with respect to a source waveform. The first power path, which may be more efficient than the second path, may transfer as much power as possible from the input to the output. The energy storage enables the second power path to make up the difference between the power available from the source and the power drawn by the first power path, and to make up the difference between the power demanded by a load and the power supplied by the first path.

A local power converter may include a controller to manipulate the operating point of a local power converter to cause the power point tracking feature of a central power converter to operate at a point determined by the controller. In some embodiments, the controller can manipulate the operating point of the local power converter by alternating between at least two modes. In some other embodiments, the controller can manipulate the operating point of the local power converter to provide a substantially constant slope. In some other embodiments, the controller can maintain a substantially constant impedance ratio. In some other embodiments, the controller enables perturbations from the power point tracking feature of the central power converter to reach the power source.

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.

Compensation for an RF detector includes components having different order temperature functions. The components are combined and may be adjusted by various numbers of user-accessible terminals to provide individual adjustment for factors such as operating frequency. In some embodiments, first and second-order temperature functions are generated independently and combined to provide a polynomial function of temperature with coefficients that may be adjusted. In other embodiments, the outputs of the function generators may be more complex functions of temperature with various adjustable parameters.
