Introduction More Stringent Energy Regulations Drive Motor Control Innovations In today's expanding industrial marketplace, the demand for electrical power is growing at an unprecedented rate.

3 More than 40% of that electrical demand comes from industrial electric motors of all sizes. Because of that phenomenon, governments and certification agencies worldwide are introducing new regulatory legislation and more stringent energy efficiency requirements on electric Motor OEMs and end users. Like many great technological innovations, there needs to be a pressing demand in the market for change. Analog Devices recognized years ago that this new era of smarter and highly efficient Motor Control Systems would be the new standard for the Motor Control industry. As part of that recognition, ADI embarked on an integrated and comprehensive Motor Control Design program in collaboration with our strategic partners, who are experts in their respective fields (MathWorks, ARM, Boston Engineering, IAR Systems , and Xilinx ), aimed at addressing the entire system architecture to achieve the greatest level of efficiency while improving system accuracy and reliability.

4 By taking a system-level view (see Figure 1) of these new challenges, ADI was able to develop products that not only exceeded the individual performance specifications but also represented the optimal interface between other functional blocks of the circuit. This system solution approach enables ADI to offer industrial-based customers a completely integrated solution that fits their specific needs while helping them meet the new, more stringent energy regulations.

7 isolated Gate Drivers Overcoming Limitations of Optocouplers and High Voltage Gate Driver Solutions isolated gate drivers provide electrical isolation as well as strong gate drive capability, which is often required for safety and robustness in many system architectures. The isolated gate driver portfolio from Analog Devices offers designers performance and reliability advantages over designs utilizing optocouplers or pulse transformers. Utilizing ADI's proven iCoupler technology, the isolated gate driver family offers the advantage of a maximum propagation delay of 50 ns, less than 5 ns channel-to-channel matching, a 50-year lifetime for 400 V rms working voltage, and galvanic isolation in a single package.
