What is a split core energy harvesting current transformer?

Current induction power supply, also known as CT power supply or current transformer power supply, draws power from the magnetic field induced by wires. The isolation transformation of the power supply mainly relies on the principle of electromagnetic induction, and can perform both voltage conversion and current conversion; At present, various types of power conversion are mainly based on voltage conversion, from high-voltage power generation and transmission to low-voltage conversion inside electrical appliances. Their basic structures are derived from the voltage conversion mode (such as PT voltage transformer, etc.).

The current induction power supply is different from common power supplies. Its theoretical basis is based on the current transformation of the electromagnetic induction principle. The premise of its energy transformation is that the primary side (often the transmission wire) has sufficient AC current transmission, and no matter how the wire current fluctuates , the power output must remain stable.

The current transformer commonly used in the power industry can be regarded as a typical application for drawing power from the power supply.
