Abstract: Module-based energy systems are provided having multiple converter-source modules. The converter-source modules can each include an energy source and a converter. The systems can further include control circuitry for the modules. The modules can be arranged in various ways to provide single phase AC, multi-phase AC, and/or DC outputs. Each module can be independently monitored and controlled.

Abstract: Example embodiments of systems, devices, and methods are provided herein for energy systems having multiple modules arranged in cascaded fashion for storing power from one or more photovoltaic sources. Each module includes an energy source and converter circuitry that selectively couples the energy source to other modules in the system over an AC interface for generating AC power or for receiving and storing power from a charge source. Each module also includes a DC interface for receiving power from one or more photovoltaic sources. Each module can be controlled by control system to route power from the photovoltaic source to that modules energy source or to the AC interface. The energy systems can be arranged in single phase or multiphase topologies with multiple serial or interconnected arrays. The energy systems can be arranged such that each module receives power from the same single photovoltaic source, or multiple photovoltaic sources.

Abstract: Example embodiments of systems, devices, and methods are provided for intraphase and interphase balancing of modular energy systems. The embodiments can be used in a broad variety of mobile and stationary applications in a broad variety of modular cascaded topologies. The embodiments can include the generation of a module status value that is representative of status information collected or determined for the module. The module status value can be an intermediate quantitative representation of the status of each module as it pertains to one or more operating characteristics sought to be balanced by the system. This intermediate quantitative representation can then be used in the generation of a modulation index for the module, which can then be used as part of a larger control technique, such as pulse width modulation, for control and balancing of the system.

Abstract: A housing and/or installation frameworks for a modular multi-level energy system includes a set of similar cabinets configured for orthogonal (e.g., vertical and horizontal) alignment of the modules. The cabinets are configured so modules of a particular phase are oriented along an axis parallel to a reference plane. Modules of the same level of the multi-level arrangement but of different phases are mounted in each cabinet, arranged such that a module for each phase is a defined distance from the reference plane. The cabinets are arranged equidistant and orthogonal to the reference plane, minimizing distance for connections between modules of the same phase across multiple cabinets, and facilitating convenient addition or removal of levels. The framework also facilitates data and reference signal connections between local control devices of the modules, and between the local control devices and a master control device for the system.

Abstract: Example embodiments of systems, devices, and methods are provided for electric vehicles that are subject to intermittent charging, such as rail-based electric vehicles, having one or more modular cascaded energy systems. The one or more modular systems can be configured to supply multiphase, single phase, and/or DC power to numerous motor and auxiliary loads of the EV. If multiple systems or subsystems are present in the EV, they can be interconnected to exchange energy between them in numerous different ways, such as through lines designated for carrying power from the intermittently connected charge source or through the presence of modules interconnected between arrays of the subsystems. The subsystems can be configured as subsystems that supply power for motor loads alone, motor loads in combination with auxiliary loads, and auxiliary loads alone.
