Characteristics, principles, classifications, usage methods, and precautions of power inductors 2

3、 Category:

Power inductors can generally be divided into two types: voltage type power inductors and current type power inductors.

1. Voltage type power inductor: Voltage type power inductors determine power factor and power by measuring the phase difference between the power supply voltage and current. It usually uses capacitors and resistors to measure phase difference.  diode,

2. Current type power inductor: Current type power inductors determine power factor and power by measuring the phase difference between the power supply current and voltage. It usually uses inductive components and capacitors to measure phase difference.

4、 Usage:

1. Connection: Connect the input terminal of the power inductor to the voltage port of the power supply, and connect the output terminal to the load.

2. Calibration: Calibration is required before using power inductors. The purpose of calibration is to ensure the accuracy and correctness of the measurement results of power inductors. Calibration usually requires the use of standard power sources and standard loads.   diode

3. Measurement: After the connection and calibration are completed, the power factor and power of the power supply can be measured. According to the type of power inductor, appropriate measurement methods and parameters can be selected.   diode
