When learning about current and voltage sources, the issue of internal resistance in the power supply often confuses many people, only remembering that when the voltage source is connected to an exter…
For an electronic system nowadays, the design of the power supply part is becoming increasingly important. I would like to discuss with you some of my own experiences on power supply design, in order to introduce ideas and make progress in power supply design.
In the forum, I saw a lot of PCB wiring problems raised by netizens. I felt the problems caused by the stepping motor wiring before. I understand this PCB wiring with common sense, which is easy to
Electric Vehicle (EV), refers to the general term for electric vehicles.
A pure electric vehicle (Battery Electric Vehicle, BEV ) refers to a vehicle powered by batteries or other energy storage devices.Fuel Cell Electric Vehicle (FCEV) refers to a vehicle that uses fuel cells as a power source.Today qihe smt pick and place machine showing EV glossary: All of the electric vehicle jargon you need to know
Whether it is a single-chip microcomputer or a microprocessor, their core is a large-scale sequential logic circuit, and the power driving the sequential logic circuit is an accurate and stable clock source-don’t underestimate the attributive “accurate and stable”,
While the transmission rate of high-speed PCB design and wiring system is steadily accelerating, it also brings some anti-interference vulnerability.
The power ground is mainly for the path of the power loop current. Generally speaking, the current flowing through the power ground is relatively large,
A power supply is an electrical device that converts the electric current that comes from a power source to the voltage value necessary for powering a load, like a motor or an electronic device.
Input resistance is a measure of the amplifier’s effect on the signal source. The larger the input resistance, the smaller the current taken by the amplifier from the signal source, and the larger the signal voltage obtained at the input terminal of the amplifier,
The sensitivity of electronic equipment is getting higher and higher, which requires the anti-interference ability of the equipment to be stronger and stronger, so PCB design has become more difficult
