摘要： Disclosed herein is an apparatus for controlling the spacing of battery cells. The apparatus monitors the temperature of the battery cells, and when a battery cell temperature value exceeds a threshold, changes the configuration of the battery cell spacing from an initial closed configuration to an open configuration using a spacer mechanism. The spacing during the closed configuration is a first distance between the battery cells, and during the open configuration is a second distance between the battery cells. The second distance is substantially large than the first distance to position the lithium ion cells further apart, lowering the probability a thermal runaway event propagating from one cell to adjacent cells. The spacer mechanism may include a telescoping or expanding frame, a motor, one or more sensors, and a controller configured to operate the mechanical spacer.

摘要： A photovoltaic module is presented, which may include a photovoltaic panel and a converter circuit having a primary input connected to the photovoltaic panel and a secondary output galvanically isolated from the primary input. The primary input may be connectible to multiple input terminals within a junction box and at least one of the input terminals may be electrically connected to a ground. The photovoltaic module may include multiple interconnected photovoltaic cells connected electrically to multiple connectors (for example bus-bars). The photovoltaic module may include input terminals operable for connecting to the connectors and an isolated converter circuit. The isolated converter circuit may include a primary input connected to the input terminals and a secondary output galvanically isolated from the primary input.

摘要： A digital average-input current-mode control loop for a DC/DC power converter. The power converter may be, for example, a buck converter, boost converter, or cascaded buck-boost converter. The purpose of the proposed control loop is to set the average converter input current to the requested current. Controlling the average input current can be relevant for various applications such as power factor correction (PFC), photovoltaic converters, and more. The method is based on predicting the inductor current base on measuring the input voltage, the output voltage, and the inductor current. A fast cycle-by-cycle control loop may be implemented. The conversion method is described for three different modes. For each mode a different control loop is used to control the average input current, ans the control loop for each of the different modes is described. Finally, the algorithm for switching between the modes is disclosed.

摘要： A pest-control structure for a photovoltaic (PV) module installation may include a support beam mounted to a support surface. The support beam may include an interface surface. A PV module may be mounted to the support beam. At least one exclusion spacer may be mounted to the support beam at the interface surface or the PV module. The at least one exclusion spacer may restrict access to an area between the PV module and the support surface.

摘要： A system and method for combining power from DC power sources. Each power source is coupled to a converter. Each converter converts input power to output power by monitoring and maintaining the input power at a maximum power point. Substantially all input power is converted to the output power, and the controlling is performed by allowing output voltage of the converter to vary. The converters are coupled in series. An inverter is connected in parallel with the series connection of the converters and inverts a DC input to the inverter from the converters into an AC output. The inverter maintains the voltage at the inverter input at a desirable voltage by varying the amount of the series current drawn from the converters. The series current and the output power of the converters, determine the output voltage at each converter.

摘要： A multi-level inverter topology is disclosed. A power converter circuit converts a DC source at its input to provide an alternating current (AC) at its output. The power converter circuit may have a controller operably attached to multiple series connections of switches. The controller may control one or more of the multiple series connections of switches to convert a DC input to provide multi-level AC voltages with DC offset across two terminals of the power converter circuit. The multi-level AC voltages with DC offset may then be converted by use of a plurality of series connections of switches to provide a single-phase AC voltage at a first output terminal with respect to at least one of a neutral potential, an earth potential, or a terminal of the power converter circuit.
