Ct Switch Power Supply Current Transformer Ac Isolation Electromagnetic

The isolation and transformation of the power supply mainly rely on the principle of electromagnetic induction, which can carry out voltage transformation and current transformation. At present, various power transformations are mainly based on voltage transformation, from high-voltage power generation and transmission to low-voltage transformation inside electrical appliances. Its basic structure They are all derived from the voltage conversion mode.

The current induction power supply is different from the common power supply. Its theoretical basis is derived from the current conversion of the electromagnetic induction principle. The premise of the energy conversion is that the primary side (usually the transmission wire) has sufficient AC current transmission, and no matter how the wire current fluctuates, The power output must remain stable.
In the power system, CT is the abbreviation of Curent Transformer, which is used to measure the magnitude of alternating current. People sometimes use its secondary output current to transform to achieve the purpose of current induction power supply. Therefore, in many occasions, current induction The power supply is called CT power supply.
