摘要： An energy conversion system and method perform active control of leakage current in multi-level grounded inverters. First and second subsystems each include positive and negative DC source terminals, at least first and second capacitors coupled between the positive and negative terminals to define a common bulk node for the respective subsystem, a DC/DC converter for regulating voltages across the capacitors, and an inverter. The inverters are coupled in parallel to an AC load. First and second grounding branches are homogenously coupled to terminals in the first and second subsystems, respectively, and to the same ground terminal. Control circuitry detects a leakage current value through the ground terminal, generates leakage current control signals for the respective DC/DC converters based at least in part on the detected leakage current value and a reference current value, and communicates the control signals to the DC/DC converters.

Through the signal proportional to the leakage current measured a feedback signal is generated to control the leakage current (Ileak).

摘要： The system provides for one or more photovoltaic panels (3) or other energy sources, connected to a series of inverters (5) in parallel, the outputs of which are connected to a load (Z) and/or to an electricity distribution grid (7). One of the inverters operates as master unit and generates a power control signal in order to track the maximum power point that can be obtained from the panels (3). The other inverters operate as slave units. The control is performed so that all the inverters absorb a variable quantity of power according to the fluctuations in the power available at the output of the photovoltaic panels (3) or other source subject to fluctuations.

摘要： An insulative blanket is sized and shaped to cover a dock leveler deck and the gaps between the deck and a surrounding dock platform to prevent the transfer of heat through the deck or across the gaps. A batten structure is combined with the blanket such that the combination forms a relatively rigid structure which can be easily placed and maintained in its desired position. The combination is raised and lowered by an attached line and a suspended overhead container is provided to further collapse the combination as it is raised and stored within the container.

摘要： A controllable electrical switch having a power system and switching device for connecting a source voltage to a load. The power system includes a switching regulator to extract energy directly off the non filtered full wave rectified input voltage to minimize the average magnitude of the current when the switching device is in the off-state. For on-state power the controllable electrical switch may include a transformer connected in series with the switching device. The controllable electrical switch and power system may be used to replace a standard two- wire or three-wire wall switch, and may be used over a wide voltage and load power range in a low cost, small package with low power dissipation.
