Motor control FPGA

Reduced cost for motion and motor control

Designing motor control and motion control systems with FGPAs and SoCs can result in significant reduction in overall cost. Motors and drives power countless industrial processes in production, assembly, packaging, robotics, computer numerical control (CNC), machine tools, pumps, and industrial fans. These motor-driven systems account for more than two-thirds of industrial energy consumption, making their efficient operations vital to factory profits. System integration: Lower bill of materials (BOM), power consumption and reliability challenges by integrating industrial networking, functional safety, encoder and power stage interfaces and, DSP control algorithms in a single device. Scalable performance: Use a single scalable platform across entire product lines. Achieve higher performance with faster and more advanced control loops that can increase overall efficiency and machinery lifetime. Functional safety: Reduce compliance time and effort. Altera is the first FPGA supplier to obtain qualification of our devices and tools under the Machinery Directive safety standard IEC 61508.

Digital Power FPGA

More flexible, less sensitive, and programmable

Digital Power controllers can offer a number of advantages over analog controllers, including flexibility, lower sensitivity, and programmability without external components. Power management is critical in all electronic applications, but it is even more critical in portable battery-powered applications. Portable electronic applications began with calculators and radios and have grown over the last decade to include popular products such as cell phones, Personal Digital Assistants (PDAs), and MP3 Players. Portability does not stop at consumer gadgets. Power management is more than simply achieving the lowest standby power dissipation possible. There are three aspects of power design: dissipation, simplicity, and transitions. Dissipation is the most obvious power management reduction objective of system designers. Power dissipation has two basic components: static power and dynamic power. In most applications, dynamic power is more important for extending battery life, while in some applications, static power is more important. Static power is most important in applications in which battery service is an inconvenience and dynamic activity is only occasional. An example in which static power is important might be a remote HVAC control panel. Simplicity is another important consideration in power management. Low dynamic or static power dissipation is desirable, but not always at any cost. The power system needs to be as simple as possible. In battery-powered systems, multiple power rails may be prohibitive. A device component that allows for a wide operating voltage range is very desirable. Transitions are also important considerations in power management. A typical power management system is constantly transitioning from one power mode to another. It is important to understand the characteristics of the components in the system as they transition from ‘on’ to ‘off’ and ‘off’ to ‘on’, as well as how they behave when ‘off’. Depending on the hot-socket characteristics of a device, a part may burn more power parasitically in the ‘off’ state than in the ‘on’ state due to poor hot-socket characteristics.

Wireless power

Demand growing for standards-compliant systems

Since the release of the Wireless Power Consortium (WPC) specification in late 2010, implementations of Qi-compliant wireless power technology have ranged from the mobile and consumer hand-held market to industrial and medical. The market demand for the convenience and safety of standards-compliant wireless power systems continues to grow rapidly with the right products and tools to help our customers quickly bring new products to market. A wireless power system consists of a charging pad (transmitter or primary) and receiver (secondary-side equipment). Coils in both the charging pad and the receiver are magnetically coupled when the two devices make contact. Power transfers from transmitter to receiver via coupled inductors (e.g. an air core transformer). The amount of power transferred is controlled by sending feedback communication (error signals) to the primary device to increase or decrease power. The transmitter coil is powered ‘off’ most of the time, only occasionally waking to see if a receiver is present. When a receiver authenticates itself, the transmitter remains powered ‘on’. 

Energy harvesting

Environmental electricity – for low power applications

Energy harvesting is a way to generate electrical energy from the ambient environment. For example, ambient light, radio waves, and temperature differences can be directly converted into electricity with solid-state components. Energy harvesting techniques are a great option for low power applications as a replacement for batteries. The amount of power that can be generated by energy harvesting is low, so applications are limited but work well for wireless sensors, wearable electronics, long term sensors, and low power applications that need to work longer than the life of a typical battery. However, the potential for sensors that can operate continuously for years, or small electronic devices that do not need to be connected to the power grid, has attracted a lot of interest and development. By enabling 20+ year battery life it is necessary to open the door to new applications that were not feasible with traditional battery-powered systems: from powering a clock with a grape, to using vehicle vibrations to power sensors on a bridge, to solar-powered sensors for wireless monitoring of a farm or winery. Leading energy-harvesting vendors, are creating a complete eco-system allowing designers to not only envision but also create a battery-less world.
