Power inductance Overview
The inductor in the general electronic circuit is a hollow coil, or a coil with a magnetic core, which can only withstand a lower voltage through a smaller current; The power inductors also have hollow coils and magnetic cores, and are mainly characterized by winding with thick wires, which can withstand tens of amps, hundreds, thousands, and even tens of thousands of amPs. Power inductors are divided magnetic cover and no magnetic cover, mainly composed of magnetic core and copper wire. In the circuit mainly plays the role of filtering and oscillating.The invention relates to an integrated high current inductor developed by Maixiang Technology, which can replace a magnetic ring coil. Its production process has changed from the original rail hydraulic type to the slide hydraulic type. The product qualification rate has been controlled at 92%. The chip power inductors, using iron powder cores, offer better temperature stability and lower cost compared to other optional cores. The shape of the chip inductor provides flexibility and variability when necessary, but at a higher cost. High flux loops are usually found in filter inductors rather than power conversion circuits. Another performance trade-off can be seen in the typical waveform of inductive current, inductive voltage (pin 14 to pin 16), and output voltage ripple. The use of smaller inductance fdv0620-0.47μh inductance produces higher peak current, and the output voltage ripple is lower than the peak value of 18mv. The ripple peak generated by the chip inductance is just over 12mv. The peak current charges the output capacitor and supplies the load current. Larger currents flow in and out of the capacitor, which will produce a higher output voltage ripple. The chip inductor is mainly used in the power filter circuit, and the inductor is the energy storage component, which is mainly used to suppress the conductive interference. Chip inductors make extensive use of inductive components and EMI filter components in PCB circuit of electronic devices. In the resonant circuit, the inductor must have high Q, narrow inductance deviation, and stable temperature coefficient to achieve the narrow band and low frequency temperature of the resonant circuit.
