    摘要: A power harvesting system including multiple parallel-connected photovoltaic strings, each photovoltaic string includes a series-connection of photovoltaic panels. Multiple voltage-compensation circuits may be connected in series respectively with the photovoltaic strings. The voltage-compensation circuits may be configured to provide respective compensation voltages to the photovoltaic strings to maximize power harvested from the photovoltaic strings. The voltage-compensation circuits may be include respective inputs which may be connected to a source of power and respective outputs which may be connected in series with the photovoltaic strings.

    摘要: Systems methods and apparatuses are disclosed herein for disconnecting MC4 connectors via a tool. The tool may comprise a holding portion and two arms. The two arms may be configured to align the tool for MC4 disconnection. The two arms may further be configured to squeeze anchoring tabs of connected MC4 connectors. Further, the two arms may be configured to extract and/or separate the connected MC4 connectors while holding the anchoring tabs in the squeezed position.

    摘要: Systems, apparatuses, and methods are described for an inverter which receives a direct current (DC) input, and outputs an alternating current (AC) output. A high AC voltage is achieved by serially connecting AC outputs from inversion modules included in the inverter. Multiple inversion stages are serially connected in order to form the AC output. Windings around a common core of the inverter may cause ripple currents to be shared by the inversion modules. Utilizing a common core enables reducing low frequency ripple currents.

    摘要: A vehicle traction device having at least one energy storage component; at least one traction component; at least one acceleration sensor including a pressure sensor, a motion sensor, a gyroscopic sensor, an accelerometer, and/or a piezoelectric sensor; and at least one deceleration sensor including a pressure sensor, a motion sensor, a gyroscopic sensor, an accelerometer, and/or a piezoelectric sensor. The at least one acceleration/deceleration sensor is responsive to an operator input, and when the operator input is applied to the at least one acceleration/deceleration sensor, the energy traction device is signaled to transfer energy from the at least one energy storage component to the forward propulsion of the vehicle, or vice versa, using the at least one traction component. The vehicle traction device may be incorporated into, for example, a wheel, a motor, and/or a transmission.
