Concerto MCU Overview Slide 6

Concerto™ will provide immediate benefits to a lot of green technologies in the market today. The trend now is that applications such as industrial drives and automation, solar, as well as server rectifiers all need to add more advanced connectivity to their solutions. Many customers that make industrial drives and work with automation need real time control for the precision they require. There is a lot of custom software that goes into these algorithms. It is not just efficiently spinning a motor to save energy. There is a lot of analysis when it comes to different aspects like the state of health of the motor, position and speed, and strength; for instance, to determine how much force to exert in a robotic hand. All of that is the responsibility of the control side. These systems also need a great deal of task management if there is an operating system, or system management which takes in the inputs of other sensors and data from communication. Communication is also a huge part of these systems. First, it is needed for things such as coordination of multiple motors in a system; a multi-jointed robotic arm for example. An arm needs to be able to pick up and move objects of varying weights, which introduces different loads on each motor. Communication between each of the motors is required to make these types of dynamic precise movements possible. Beyond communication within the system, industrial drive and automation systems need high speed connectivity, like Ethernet, to remote control centers. Another more pervasive technology that is used every day is servers and data centers. These consume a huge amount of energy, for which even a single percentage point of efficiency increase can save millions of dollars in electricity consumption. But increasing efficiency is not easy. Servers are complex systems with multiple power rails and multiple subsystems. For example, a server rack may need to be supplied with 5 V, 12 V, 24 V, and 48 V rails. Each of these rails needs to have clean, precise power to maximize reliability. This is where the C28x shines, the math capabilities and precision peripherals lend themselves perfectly to these requirements. By being able to drive multiple rails independently, the C28x side of Concerto will be able to handle different loads on each of the rails, and dynamically adjust each profile to maximize efficiency. However, that is only half of the story. There is also a need for system management, to balance the loads, to run diagnostics, to detect irregularities and quickly switch to UPS backup systems without skipping a beat. All of this information needs to be communicated back to a control center as well. The Cortex™-M3 core can execute on every one of these aspects, ensuring that the C28x can focus on the power conversion. This same technology applies to other applications requiring efficient power conversion, such as renewable energy.
