Thermal Management Strategies for Long-Lived Vehicle Lighting

Insensitivity to vibration, long life, high energy efficiency, and the possibility of total control of the light source are key factors for LED applications in vehicles. Compared with incandescent bulbs, LEDs are insensitive to mechanical vibrations, and LEDs’ ease of control makes them a natural choice for intelligent automotive lighting systems that adapt to vehicle…

Wide-Bandgap Devices Optimize Mobility, Autonomy for EVs, Robotics

Automotive and industrial electronics require high-performance solutions that deliver energy efficiency and reliability while reducing device dimensions. In recent years, as their cost has come down, wide-bandgap semiconductors such as gallium nitride (GaN) and silicon carbide (SiC) devices have become increasingly popular replacements for silicon switches in these applications. The most popular applications for GaN…

Robust MEMS Sensors Are a Sound Choice for Audio

Microelectromechanical system (MEMS) technology offers robustness and reliability for microphones and loudspeakers used in consumer voice-control implementations as well as for the more extreme environments of industrial applications. The sensors have become increasingly integrated with other components of the audio signal-processing chain, allowing smaller microphones with analog or digital output. Inside the package, the transducer…

Transducer Options for Safe, Precise Current Sensing

Current measurement is an integral part of power electronics. Power supply designers, battery management systems, and motorized drives often need to measure current accurately. Current transducers (not to be confused with current transformers) can measure both DC and AC. Current transducers are most often based on closed-loop Hall-effect or closed-loop flux-gate technology. Typically, power requirements…

Motor Speed Control Using Hall-Effect Sensors

A Hall-effect sensor varies its output voltage in response to a magnetic field. Hall-effect devices are used as proximity sensors and for positioning, speed, and current detection. They are widely used in motor control systems. A Hall-effect sensor is a long-lasting solution because there are no mechanical parts to wear down over time. The integrated…

High-Performance Design for Ultrasound Sensors

Ultrasound waves are sound waves with frequencies above 20 kHz, which is the average upper frequency limit detectable by the human ear. Ultrasound waves are subject to reflection, refraction, and diffraction phenomena and can be characterized by their frequency, wavelength, and propagation speed, as well as the attenuation that occurs as the wave passes through…

High-Performance Sensors Bring Gesture Control to Vehicles

Gesture-recognition technologies let users control electronics by moving their hands, fingers, head, or body. In a typical implementation, one or more optical-acquisition sensors interpret the images to determine the action of the user, drawing on a mode of communication to introduce a certain intuitiveness and ease of interaction. Gesture recognition is especially important in situations…

E-Mobility Informs the Future of Power at PCIM

More than 12,000 visitors and 500 exhibitors gathered in Nuremberg, Germany, last month for the annual PCIM Europe tradeshow and conference, where they shared information on emerging power electronics design strategies, technologies, and products for automotive, e-mobility, and industrial markets. The evolving discipline of electromobility is a perennial focus for PCIM, with more than 250…
