Isolation Architectures in Motor Control


Watch Demo: Analog Devices' Isolation Technology for Industrial Motor Control

This demo shows various elements within a motor drive where isolation is critical to the system performance. Multiple ADI isolation products based on iCoupler® Technology are demonstrated in applications such as isolated analog-to-digital conversion, isolated gate drive, signal isolation, and isolated board-to-board and backplane communication.

Non-ideal Effects in a Motor Drive

The demo illustrates the topics in the paper presentation “A system approach to understanding the impact of non-ideal effects in a motor drive current loop”.

The demo uses ADSP-CM408 mixed-signal controller and a 400V PM-motor to show how system performance is affected by non-ideal effects in the current loop. See how the demonstrated feedback circuit design can mitigate the non-ideal effects.

Energy Harvesting and Other DC-to-DC Conversion


Watch Demo: Energy Harvesting with Analog Devices' ADP5091

The new generation energy harvesting power converter, ADP5091, generates two system voltages with only one inductor in a very efficient manner. Its low power consumption, high efficiency based on (MPPT) Maximum Peak Power Point Tracking and fast cold start scheme enable IoT sensor applications without the need for batteries. Also we show negative voltage generation from a positive supply voltage with the ADP5070. Its adjustable slew rate function reduces switching noise significantly for low noise applications. Last but not least, the ADP2360, a 60V input voltage, 50mA ultra high efficient buck regulator for process control applications using HART modems is shown. It combines highest efficiency with low noise, which is required especially inHART modem process control applications. PV Inverter

Embedding Safety into Power Conversion for Solar, Storage, and eV Infrastructure



Watch Demo: ADSP-CM41x Mixed-Signal Control Processors for Power Conversion

Analog Devices will showcase its new Precision Power Conversion Platform targeted at next generation applications including solar PV inverters, Solar+Storage and Electric Vehicle Infrastructure.  This platform is centered on our breakthrough family of highly optimized mixed-signal control processors seamlessly integrated with other critical signal chain components, including shunt based Isolated Current Sensors and Isolated Gate Drivers.

This demo highlights the industry’s first TUV attested innovative single chip dual independent core safety concept that provides a fully redundant second signal path, and dismissing the usual need for a separate supervisory processor core.  This safety based integration reduces system cost, allows for design simplicity while still maintaining full compliance with VDE-AR-N4105 safety standard.

A system approach to understanding the impact of non-ideal effects in a motor drive current loop

An essential part of any digitally controlled motor drive is phase current feedback. The quality of the measurement directly relates to system parameters such as torque ripple and torque settling  time. While there is strong correlation between system performance and phase current measurement, it is difficult to translate into hard requirements to the feedback system. From a system point of view, this article discusses how to design a feedback system optimized for motor control. Error sources are identified and mitigation effects are discussed.

Digital Power Controllers Improve Reliability and Availability of DC/DC Converters

Modern digital power controllers do not only improve the power efficiency of converters, they can also en¬hance their reliability and availability. New features like volt-second-balance, matched cycle-by-cycle current limiting, digital current sharing and nonlinear gain control for fast transient response can only be realized by digital controllers.

The volt-second-balance helps equalizing the current in the power transformer to avoid successive accumu¬lation of magnetic flux, thus avoiding transformer satu¬ration and overheating. Matched cycle-by-cycle current limiting avoids transformer imbalance during over current condition. Digital current sharing provides ac¬curate and EMI-robust control of converters working in parallel. Nonlinear gain enhances the system response on fast loads transients.

Functional safety for integrated circuits used in variable speed drives

Functional safety is the branch of safety related to correct functioning of electrical and electronic systems. Variable speed drives now play an important part in implementing functional safety. Previously functional safety for motor control applications was realized using safety relays and contactors external to the drive. But with safety integrated in the drive safety functions such as STO and SLS can be implemented within the drive offering productivity enhancements on the factory floor. Integrated safety requires the use of integrated circuits but interpreting the functional safety requirements for integrated circuits used in variable speed drives is challenging. Ideally all such ICs would be assessed to IEC 61508 but this would be expensive and is not demanded by the standards. Based on my experience as a member of IEC SC22G/MT12 working on the functional safety for variable speed drives standard, this paper will attempt to summarize what guidance is available for integrated circuits being used in the design of variable speed drives.
