DC Power Supply True RMS Measurements

The ripple and noise of a DC power supply are important parameters for evaluating the quality of the power supply, and they reflect the instability and interference of the power supply output. Large ripple or noise may lead to unstable system operation, increased sensor error, distortion of analog signals, and other problems. Therefore, it is very important to properly measure and evaluate ripple and noise levels when designing and selecting power supplies. This article will describe how to test DC power su....

Selection and implementation of BLDC control strategy

Understanding the difference between trapezoidal, sinusoidal and field oriented control can help engineers understand the value of field oriented control (FOC) and the options available to optimize their designs. BLDC motors are smaller, lighter and quieter than traditional brushed DC motors, while also improving reliability and energy efficiency in consumer, industrial, automotive and medical applications. Their brushless construction simplifies equipment design and maintenance by eliminating mechanical we....

TRM Current Sensor VS Hall Sensor

Current sensors, as important components in power systems and electronic equipment, play a key role in measuring the current in circuits. They convert current signals into output signals that are proportional to them, thus realizing current monitoring, control and protection. Among current sensors, TRM (Tunnel Magneto-Resistance) current sensors and Hall sensors are two common types, which have certain differences in their operating principles, performance characteristics and application scenarios. TRM Cu....

Are cars actually going to use open source software?

Open source ecosystem is an important engine to promote software technology innovation, it can be said that many great software and OS in the world now rely on open source, to prosperity. In the field of autonomous driving platform, there are also many open source platforms, of which Autoware is the most famous, it can be said that its status in the world of autonomous driving is no less than “Linux”. Of course, it should not be interpreted as an OS, it is actually a set of software libraries an....

What are the control methods for PWM control?

Basic principle of PWM control (Pulse Width Modulation) The control method is to control the on-off of the switching device of the inverter circuit, so that a series of pulses of equal amplitude are obtained at the output, and these pulses are used to replace the sinusoidal waveform or the desired waveform, that is, multiple pulses are generated in half a cycle of the output waveform, so that the equivalent voltage of the pulses is a sinusoidal waveform, and the obtained output is smooth and with fewer low ....

This power technology, it's about to explode

Processors and data center architectures are changing to meet the higher voltage demands of servers running AI and large language models (LLMs). At one time, servers ran on a few hundred watts of power. But things have changed dramatically in the last few decades as the amount of data to be processed has increased dramatically and users demand faster data processing.NVIDIA's Grace Blackwell chips consume 5 to 6 kilowatts, which is roughly 10 times the total power consumed by servers in the past.1 The power ....
