摘要： A load control device for controlling power delivered from a power source to an electrical load may comprise a control circuit configured to control the load regulation circuit to control the power delivered to the electrical load. The control circuit may be configured to operate in an AC mode when an input voltage is an AC voltage and in a DC mode when the input voltage is a DC voltage. The control circuit may be configured to disable the power converter in the DC mode. The control circuit may be configured to render a controllable switching circuit conductive in the AC mode, and non-conductive in the DC mode. The rectifier circuit may be configured to rectify the input voltage to generate a rectified voltage when the input voltage is an AC voltage, and to pass through the input voltage when the input voltage is a DC voltage.

摘要： A switch includes a first terminal, a second terminal, and a third terminal. The switch includes an output node coupled to the second terminal and the third terminal. The switch includes a contactor coupled to the first terminal and movable between at least a first position and a second position. The first terminal is coupled to the second terminal when the contactor is in the first position. The first terminal is coupled to the third terminal when the contactor is in the second position. When the contactor is in the first position, the switch is configured to provide direct current power at the output node. When the contactor is in the second position, the switch is configured to provide alternating current power at the output node.

摘要： A power conversion system includes a first converter configured to convert an input voltage into discrete voltage levels, and provide each discrete voltage level at a corresponding output terminal. The power conversion system further includes a second converter configured to convert the discrete voltages into modulated voltages. The power conversion system further includes a selection unit configured to alternatively output each of the modulated voltage voltages across a pair of output terminals.

摘要： A method for driving an electro-optical functional layer by a control, the functional layer being applied on a substrate and being variable in its transmissive and/or reflective properties by applying an electric field, the control unit having a supply voltage input and a feed output, and a voltage measuring system and an energy store, includes measuring a voltage actually available at the supply voltage input, if the available voltage is greater than a reference value, driving the functional layer with an AC voltage via the feed output, the energy store being charged at least in sections, if the available voltage is less than or equal to a reference value, driving the functional layer with a DC voltage via the feed output. At least part of the energy for the driving is drawn from the energy store. The DC voltage is less than the peak value of the AC voltage.

摘要： A switching device is provided. The apparatus includes a switching circuit and a noise filter. The switching circuit is capable of switching a connection destination of a first power conversion circuit other than a second power conversion circuit among the plurality of power conversion circuits between a phase corresponding to the first power conversion circuit and a certain phase of the external power supply. The second power conversion circuit corresponds to the certain phase of the external power supply. In the noise filter, a capacitor is provided on a side of the multiple-phase AC supply of the switching circuit.

摘要： A voltage doubling circuit that increases input voltage to higher output voltage connected to a variable frequency drive. The voltage doubling circuit can include a power input that receives the input voltage from a power source and a first capacitor bank and a second capacitor bank connected with the power input. A current-limiting surge suppressor is positioned between the power input and the first capacitor bank and the second capacitor bank. The current-limiting surge suppressor includes a first current-limiting path and a second bypass path. A drain, when operable, dissipates the charge of the first capacitor bank and the second capacitor bank. A variable frequency drive (VFD) is operable in response to the higher voltage output from the first capacitor bank and the second capacitor bank.

摘要： The invention relates to a system for combining multiple power sources into a single in-phase AC current and related methods. According to an illustrative embodiment of the present disclosure, multiple out of phase AC power sources are provided, individually converted into DC currents, and combined in parallel to create a single DC current. The single DC current is then converted to an AC current, leaving a single in-phase AC current.

摘要： A multiphase converter topology is used for the transmission of electrical energy from an AC voltage input with m grid phase connections to a DC voltage output or vice versa. It has a power part with half-bridges for switching currents, an AC voltage filter between the power part and the AC voltage input, and DC voltage block(s) connected between the power part and the DC output. The AC voltage filter has alternating voltage filter stage(s) with m+1 input connections, m+1 output connections and a ground connection. The m grid phase connections are thereby connected in parallel to one another and form a first phase connection for the connection of a single-phase AC voltage. A neutral conductor connection of the AC voltage filter forms a neutral conductor connection of the AC voltage input and a second phase connection for the connection of the single-phase AC voltage.
