■ Product Introduction
JX-LL Series DC-link capacitors have many advantages, such as withstanding high voltage and current stressing, low-impedance, low inductance, low loss of capacitance, low leakage current, temperature for good performance, fast charge and discharge, long service life(About 100,000 hours), safety explosion-proof and good stability, non-polarized easy installation etc, which is widely used in the power electronics industry. The main function as follows:
1.In the inverter circuit is mainly for smooth filtering the output voltage of the rectifier.
2.Absorb high amplitude pulse current which is obtained from the “DC-Link” by the inverter, and prevent from generating high amplitude pulse voltage on the impedance of “DC-Link”, in order to keep voltage fluctuations of the DC-Link in the allowance range.
3.Prevent from overshoot of “DC-Link” voltage and effects of transient overvoltage on IGBT.
