What is a Motor Starter?26 December 2025
A motor starter is an electrical system used to safely start and stop a motor. Like a relay, the motor starter turns power on/off, which offers low voltage and overcurrent safety, as opposed to a relay.
MOSFET vs. IGBT: Characteristics, Structure and Market Analysis25 December 2025
With the rise of new energy in recent years, the market demand for MOSFETs and IGBTs is increasing steeply. Generally used as switching devices, they are widely used in electronic circuits. MOSFETs and IGBTs are relatively similar in appearance and characteristics parameters. So what is the difference between MOSFETs and IGBTs?
Top 10 Popular Semiconductor Companies in 202525 December 2025
The semiconductor industry is made up of businesses that design and manufacture semiconductors and semiconductor devices like transistors and integrated circuits. It was founded around 1960, when semiconductor device manufacture became a viable enterprise. Since then, the industry's yearly semiconductor sales revenue has risen to more over $481 billion in 2018. This article presents the top 10 most popular semiconductor companies in 2022.
Rheostat Basics: Types, Principle and Functions25 December 2025
A rheostat is a device that can adjust the size of the resistance and can be connected to the circuit to adjust the size of the current. A general rheostat is composed of a wire with a larger resistance and a device that can change the contact point to adjust the effective length of the resistance wire. Rheostat can limit the current and protect the circuit, and change the voltage distribution in the circuit.
Surge Protection Devices (SPD): The Complete 2025 Guide25 December 2025
A surge protection device (SPD), also called a surge protector, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When a spike current or voltage is suddenly generated in the electrical circuit or communication circuit due to external interference, the surge protection device can conduct and shunt in a very short time, so as to prevent the surge from damaging other equipment in the circuit.
