Abstract: Leakage current through stray or parasitic capacitance (which is particularly large in devices such as photovoltaic cell arrays and which are damaged by such leakage currents) due to common mode switching noise in a full bridge single phase power converter is reduced at high frequencies by magnetically coupling the two phase legs on the AC side of the power converter and connecting mid points of the AC and DC sides of the power converter and is reduced at low frequencies by use of a feedback arrangement that modifies sinusoidal modulation of the switches of the full bridge converter to function as an active filter. The magnetic coupling for the two phase legs is designed in a simple manner to avoid saturation based on volt-second considerations.

Abstract: DC link capacitance in a bi-directional AC/DC power converter using a full-bridge or H-bridge switching circuit can be greatly reduced and the power density of the power converter correspondingly increased by inclusion of a bi-directional synchronous rectifier (SR) DC/DC converter as a second stage of the power converter and controlling the second stage with a control loop having a transfer function common to both buck and boost modes of operation of the bi-directional SR DC/DC converter and a resonant transfer function to increase gain at the ripple voltage frequency (twice the AC line frequency) to control the duty cycle of the switches of the bi-directional SR DC/DC stage and controlling the duty cycle of the switches of the full-bridge or H-bridge switching circuit using a control loop including a notch filter at the ripple voltage frequency.

Abstract: A system and method support smart scheduling for an oil, gas and chemical process system with a plurality of facility units. A subset of the process facility units can be selected from the plurality of process facility units. A partial scheduling calculation can be performed on the selected subset of process facility units, independently from the rest of the chemical process facility units. A schedule can be calculated for the subset of chemical process facility units, based on the partial scheduling calculation.

Abstract: Message handshaking and integration may be provided. A message may be created by a client in a first format. The client may determine whether a server in communication with the client is operable to deliver the message in a second format. If so, the client may provide the message, in the first format, to the server for delivering to at least one recipient in the second format.

Abstract: A liquid crystal display device includes a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer sandwiched between the first and second substrate. One of the substrates (3) includes a first metal layer (31), an insulative layer (32), and a second metal layer (33) disposed in that order. The first metal layer has an electric potential lower than that of the second metal layer. The first metal layer, the insulative layer, and the second metal layer cooperatively form a filter capacitor. With this configuration, the filter capacitor filters the electrical current passed through the second metal layer. Thus, noise induced by electromagnetic interference is filtrated, which enables the internal signal transmission of the liquid crystal display device to be more reliable.
