Problems solved by technology

Usually, an air conditioner frequency conversion circuit needs two active PFC inductors, and at the same time, it uses a lot of iron minerals (the amount of two PFC iron ore is 103g); in addition, the current active PFC is used in the active PFC circuit. The frequency of its own impedance application is low, and it can only work at a frequency below 250KHZ, which cannot achieve a good filtering effect

Abstract

The invention provides a PFC inductor and a variable-frequency air conditioner. The PFC inductor comprises a base, a magnetic core, a separator and a coil, wherein the edge of the magnetic core is fixedly connected with the base; the coil is wound around the magnetic core; the separator is arranged in the diameter of the magnetic core in a direction perpendicular to the base, and is fixedly connected with the magnetic core; fixing parts are arranged on the two sides of the separator, and the two end portions of the coil penetrate through the two fixing parts correspondingly one to one and then are fixed on the base. Due to the adopted structure, the impedance of the PFC inductor is higher than the impedance of two common PFC inductors in the prior art by more than 20%; meanwhile, the self-resonance frequency on the circuit is increased to about 320KHz from the original 270KHz, thereby inhibiting clutter signals generated by the circuit, and therefore, the filtering application effect is improved.

Description

technical field [0001] The invention relates to the field of inductance, in particular to a PFC inductance and an inverter air conditioner. Background technique [0002] In the field of frequency conversion air conditioners, PFC (Power Factor Correction, power factor correction) inductors are widely used, and the power factor of commonly used active PFC inductors can reach more than 98%, but the cost is relatively high. Usually, an air conditioner frequency conversion circuit needs two active PFC inductors, and at the same time, it uses a lot of iron minerals (the amount of two PFC iron ore is 103g); in addition, the current active PFC is used in the active PFC circuit. The frequency of its own impedance application is low, and it can only work at a frequency below 250KHZ, which cannot achieve a good filtering effect. Contents of the invention [0003] The invention provides a PFC inductor and frequency conversion air conditioner with simple structure, low cost, high impe...
