A generator-rectifier system and grid interface includes an active rectifier that accepts an input from an ac port of a multi-port permanent magnet synchronous generator. Passive rectifiers are connected to the others of the plurality of ac ports. Connections provide outputs of the active and passive rectifiers. A first converter operates at a fixed duty ratio driven by the outputs to interface with a dc grid or at a low grid frequency switching waveform to create a grid frequency ac output to interface with an ac grid. A second converter is connected the output of the active rectifier, and is controlled at a variable duty ratio to interface with the dc grid or an above-grid frequency switching waveform to create an above-grid frequency ac waveform to interface with an ac grid. Connections provide a serial stack of outputs of the first and second converters.

Example embodiments relate generally to systems and methods for continuous data protection (CDP) and more specifically to an input and output (I/O) filtering framework and log management system to seek a near-zero recovery point objective (RPO).

This disclosure relates AC-to-DC rectification and power flow control of electrical power generators. An integrated rectifier-generator AC-DC conversion circuit and system are disclosed for providing a regulated DC output. The integrated rectifier-generator AC-DC conversion circuit and system may include serially stacked passive and active rectifiers connected to multiple AC ports of an electrical power generator driven by mechanical energy captured by an energy harvester. The integrated rectifier-generator AC-DC conversion circuit and system may be configured to perform active ripple control and a maximum power tracking from the energy harvester by controlling a fraction of an overall power that flow through the active rectifier.

Methods and systems are provided for an engine. A condition of the engine may be diagnosed based on information provided by signals from a generator operationally connected to the engine and/or other signals associated with the engine. Different types of degradation may be distinguished based on discerning characteristics within the information. Thus, a degraded engine component may be identified in a manner that reduces service induced delay.

Methods and systems for improving the read and write performance of a distributed file system while limiting memory usage are described. The type of error correcting scheme applied to data, the partitioning of the data into data chunks, and the sizes of data slices within each of the data chunks used for storing electronic files within the distributed file system may be dynamically adjusted over time to optimize for fast IO performance while limiting memory usage (e.g., requiring less than 256 MB of RAM to generate and store code blocks). The file size of an electronic file to be stored, the amount of available memory for generating code blocks, and the amount of available disk space to store the electronic file may be used to set the data sizes of the data slices and the type of erasure code applied to data blocks associated with the data slices.
