Fixed inductors are electronic components that allow electric current to flow in one direction while blocking current in the other direction. CH-6 are one type of fixed inductor and their application field and working principle are as follows.

Application Field

The CH-6 fixed inductor is designed for use in switching regulators, resonant converters, and EMI filter applications. They are ideal for low-ripple, high-current applications and are ideal for DC-DC converters, rectifiers, and DC-AC inverters. Aside from these applications, CH-6 fixed inductors are well suited for all switched mode power supplies, high-speed outputs, and other portable electronics.

Working Principle

CH-6 fixed inductors use a combination of ferrite core and winding to create an inductor. The ferrite core acts as a magnetizing material and is used to create an electromagnetic field. The winding is used to create a winding wire that carries an electrical current. As the current passes through the winding, a magnetic field is generated. This magnetic field interacts with the core, causing the CH-6 inductor to resist the flow of current.

In a DC circuit, the CH-6 inductor provides a “back EMF” affect on the current, reducing the amount of current that can be delivered to the load. This effect is also used in AC circuits to generate power-factor correction by increasing the inductive reactance at a frequency where reactive losses are present. The inductive reactance increases with frequency, resulting in lower voltages in the DC output.

In switching circuits, the CH-6 inductor can also be used to absorb noise and reduce ripple. When the switching current is high, the inductor acts as a low pass filter, removing high-frequency noise and reducing ripple. In addition, the CH-6 can also be used to reduce EMI generated by the switching action by reducing the amount of current and voltage transitions.

In summary, CH-6 fixed inductors are widely used in various applications such as switching regulators, resonant converters, high-speed outputs, EMI filters, and DC-DC converters. They use a combination of ferrite core and winding to create an inductor that is able to provide a back EMF and provide power-factor correction in AC circuits. In addition, the CH-6 can also be used to reduce noise and ripple in switching circuits.
