DC filter capacitor

DC support capacitor, also known as DC-Link capacitor. A DC supporting capacitor is a kind of passive device. DC link capacitor, we mainly use polypropylene film dielectric DC supporting capacitor, having a high withstand voltage, high current, low impedance, low inductance, capacity loss, leakage current and low temperature performance, fast charging and discharging, long service life (about 100 thousand hours), good stability, no safety the polarity of the advantages of easy installation. Is widely used in the power electronics industry.

UV capacitor special for ultraviolet lamp CBB39

1 in the inverter circuit is mainly on the output voltage of the rectifier smoothing filter.
2 absorb from the inverter to the "DC-Link" high amplitude pulse current, prevent it in the "DC-Link" of the impedance
A high amplitude pulse voltage is generated to keep the voltage fluctuation on the DC bus to be kept in the allowable range.
3 to prevent from the "DC-Link" of the voltage overshoot and instantaneous over voltage on the IGBT
