Current Sense TransformersCurrent sense transformers are devices that are used to measure the flow of electrical current in a circuit. These transformers use the principles of electromagnetic induction to convert the current in a circuit into a voltage, which can then be measured by a current measurement instrument. Current sense transformers are commonly used in applications such as power supply circuits, motor drives, and DC-DC converters. These devices are designed to have a high degree of accuracy and low insertion loss, so that they do not significantly affect the performance of the circuit in which they are used.
