FAQ on servo motors: part 2
The servo motor is an older precise-positioning motor arrangement now facing some competition from the stepper motor. Part 1 of this article introduced the concept of servo motors along with servo amplifiers and servo controllers. This part continues that exploration. Q: What’s the history of servo motors? A: There were purely mechanical, closed-loop servo systems […]
FAQ on servo motors: part 1
The servo motor is an older precise-positioning motor arrangement now facing some competition from the stepper motor. When engineers need precise positioning of a motor’s shaft (rotor) angle and associated mechanical system, their first thought in many cases may be to use a stepper motor (aka “stepper”). That makes sense, as stepper motors have the […]
How is AI being used to improve electric vehicle efficiency?
Electric vehicles (EVs) are all about reducing carbon emissions. Artificial intelligence (AI) can help. This FAQ looks at a few examples like how AI and machine learning (ML) can be used to make context-aware operational recommendations to EV drivers for extending EV battery lifetime and how AI can work together with wide bandgap semiconductors (WBGs) […]
What tools are there to reduce AI power consumption?
Artificial intelligence (AI) can be used to maximize energy efficiency in a wide range of applications like renewable energy integration, 5G networks, electric vehicles, and even computer processing units (CPUs), yet AI itself can be highly energy-intensive to train and use. The good news is that there are tools available to reduce AI power consumption. […]
How can AI help maximize energy efficiency in 5G systems?
Energy is a significant cost in 5G telecom systems, and saving energy is good for the environment and business. In a typical 5G installation, 80% of the energy is consumed by the radio access network (RAN) equipment; the remaining 20% is needed for transport, core network functions like mobility management, routing, security, policy control, charging, […]
How is AI enabling the decarbonization of the utility grid?
The electrification of transportation, Industry 4.0, communications, agriculture, and other industries compliments the decarbonization of the utility grid to meaningfully reduce Co2 emissions. Integration of renewable energy sources will be a key to decarbonization of the grid, and artificial intelligence (AI) and machine learning (ML) will be used to enable wider integration of renewable energy. […]
How can AI enhance DVFS in processor power management?
Dynamic voltage and frequency scaling (DVFS) is a common energy-saving technique used in computer processor ICs based on the quadratic relationship between power consumption and operating voltage and the linear relationship between power consumption and frequency. It reacts to changing operating demands on the processor to minimize energy consumption. The addition of artificial intelligence (AI) […]
Power sequencing — options and tradeoffs: part 2
Proper sequencing of the multiple power rails in a system is a critical function and can be accomplished using different approaches. For applications with many rails, complicated sequencing requirements may require many additional components. There are two paths to resolving this advanced sequencing challenge, both offering the needed capabilities. One is based on a user-programmed […]
Power sequencing — options and tradeoffs: part 1
Proper sequencing of the multiple power rails in a system is a critical function and can be accomplished using different approaches. Experienced designers know that one of the riskiest periods in a product’s operating cycle is when power is turned on. This power-up phase is when each of the multiple power rails must come up […]
