Fusible Link

What Is a Fusible Link?

A fusible link is a type of overcurrent protection device used in electrical circuits and electronic devices.

Typically, it consists of a thin wire or strip made of conductive material, designed to break when the current exceeds a predetermined threshold. By breaking the circuit, it interrupts the flow of current, thereby protecting the circuit or device from overcurrent.

Fusible links are used in various applications such as electronic devices, electrical wiring, and automotive electrical systems, serving to prevent damage to equipment due to overcurrent and the risk of fire from component overheating. When selecting a fusible link, factors such as current capacity, tripping characteristics, and size are taken into consideration.

Pulse Width Modulator Circuit

What Is a Pulse Width Modulator Circuit?

A pulse width modulator circuit, or PWM circuit, is a circuit that modulates a signal by varying the pulse width of the input signal.

Typically, it generates a pulse voltage with a variable duty cycle, and by changing the width of this pulse train, it transmits or controls the signal’s information. For example, it can convert analog signals to digital signals using a pulse train with a variable duty cycle, or it can be used for power control in power conversion circuits.

PWM circuits are used in various applications, particularly playing important roles in fields such as power control, communication, and motor control. The design of PWM circuits varies depending on the application, and in some cases, high precision and fast response are required.
