In electronic components, Coupler is a component that transmits signals or power between two electrical circuits.
Coupler separates the electrical characteristics of each circuit to enable stable signal transmission.
In general, couplers are composed of two types: an optical method using light and an electrical method.
The optical coupler works by using the photovoltaic effect. In other words, when an electrical signal meets light, the electrical signal is converted and transmitted according to the wavelength of the light.
Electrical couplers work by the interaction of electromagnetic fields.
It is composed of a circuit that is electrically separated from the circuit that transmits the electrical signal, and is in contact with each circuit at a certain distance, and the electrical signal is transmitted using this.
Coupler guarantees circuit isolation and minimizes voltage or current differences between circuits to enable stable signal transmission.
These couplers are used in power conversion circuits or control circuits to ensure stable voltage and current supply, and to improve circuit signal quality by minimizing electrical noise.
