Industrial

Avago Technologies industrial solutions help provide elements of a closed loop motor control system. Avago products cover a number of the elements of motor control systems including current sensing and control of the motor, encoders to sense the position and speed of the motor, and communications interfaces that couple the motor control logic to other parts of system.

Avago offers multiple products ideal for elements of an elevator control system. The motor controls require IGBT gate drivers and isolation amplifiers for the variable current and voltage rectifiers and inverters used in controlling the drive and door motors. Optical encoders are used in the door mechanisms, and digital optocouplers can be used to electrically isolate input lines into the control unit. Inside the elevator cars, illumination LEDs such as the Moonstone Series LEDs can be used for general illumination and ChipLEDs can be used for backlighting and indicator illumination while different size seven-segment displays are available for control panel indicators such as floor level.

Avago Technologies provides solutions for industrial networking applications such as industrial valve control units. Optocouplers are used to maintain data integrity, thereby eliminating ground loop current and common mode noise. We also provide ultichannel and bi-directional optocouplers that operate at both 3V and 5V. Optocouplers will commonly be used where a copperbased network is being used.

To meet longer run networking needs, the Avago plastic optical fiber (POF) based solutions are a good fit because the fiber can be run very close to EMI producing devices without compromising the data link.

Control of the actual valve actuators (usually solenoids) is achieved using isolated relay coil drivers which provide electrical isolation.

As electrical power grids evolve towards smart grids, areas of automation include advanced HVDC transmission and AC grid monitoring and control as well as the ability to handle distributed alternative power generation that varies in amount of power generated throughout the day. The automation to accommodate smart grid control and switching is requiring better control communications and new power control elements.

Example applications in smart grid systems include communication between different control elements using optical fiber or electrically isolated links, control of IGBT or power MOSFET drivers in remote rectifier, inverter, and AC switching equipment, fiber-based optically powered current transducers (OPCTs), control of remote solenoids, and GPS integration for precise time and location information.

Smart meters provide a remote read-out of consumption information in real time and allow utilities and consumers to better track usage. The objective is to modify consumption patterns as well as enabling realtime pricing and demand management.

Avago offers products that allow measurement of voltage and current conditions, help interface the smart meter to a variety of RF communications standards, and allow the integration of GPS capability into the meter for precise time and location measurements.

Avago Technologies provides solutions for industrial networking applications. Optocouplers are used to maintain data integrity, thereby eliminating group loop current and common mode noise. Avago Technologies offers customers value with multi-channel and bidirectional optocouplers, as well as a series of digital optocouplers that operate at both 3V and 5V. For longer runs, optical fiber-based solutions are ideal as the fiber can be run very close to EMI producing devices without compromising the data link. Industrial Ethernet protocols are becoming more widely used, including standards such as ProfiNet, Interbus, and EtherCat. It is likely that fiber optic based links and electrically isolated links using digital optocouplers will co-exist for some time, and Avago offers solutions for both choices.

Solar photovoltaic (PV) cells convert sunlight into electricity. The world's largest solar photovoltaic power stations (MW Farms) exist in Europe and are typically integrated with agriculture and use innovative tracking systems that follow the sun's daily path across the sky to generate more electricity than conventional fixed-mounted systems.

A building-integrated photovoltaic (BIPV) system involves integrating photovoltaic modules into the building for example by replacing the roofs, walls or windows. The complete BIPV consists of the PV modules, charge controller, power storage and conversion system.

Avago Technologies provides gate drive optocouplers for driving power IGBT/MOSFET and isolation amplifiers for current sensing in the power conversion system. The gate drive optocouplers isolation solutions provide reliable and efficient driver while the isolation amplifiers provide precise and stable voltage and current monitoring in noisy, high voltage environment. Avago Technologies also provide high speed digital optocouplers for communications, control and data collections between these high voltage systems and the processors.

Avago Technologies provides solutions for industrial networking applications including security and surveillance systems. The various elements of the system need to be interconnected, often over long distances, and managed by a central processing system that analyzes image data, detects intrusion alerts, and manages storage to digital video storage arrays.

Avago Technologies provides solutions for several areas of medical MRI and CAT scan systems. The patient table positioning systems use closed-loop feedback motors and require accurate motion and position information in order to accurately move and position the patient. Avago products suitable for motor control include IGBT gate drivers, digital optocouplers, and rotary encoders. The communication from the control unit to the RF and sense coils requires a large amount of image data to be transmitted in an electrically noisy environment. This is a good fit for Avago fiber optic transmitter and receivers.

Avago Technologies provides several solutions for electric or diesel-electric powered trains and locomotives including inverters and motor controls that can use Avago IGBT gate drivers and isolation amplifiers.

Communication between the different control modules, displays, and operating devices within the train or locomotive occurs in an environment with electromagnetic interference (EMI). Applications within this type of noisy environment rely on the use of a Multifunction Vehicles Bus (MVB) and Avago optical transceivers are often used for the long link distances and resistance to an electromagneticfilled environment where the MVB operates.
