Application: ZZMJ DC support capacitor is widely used in power electronic circuits of PV inverter, HV frequency converter, electric locomotive, electric vehicle, SVG, APF and other systems. It serves functions including filtering, energy storage, and protection, such as smoothing the output voltage of rectifier and absorbing high-amplitude ripple currents from DC busbars.

Features:

1. Self-healing capability: automatically restores insulation after dielectric breakdown during operation.

2. Withstands high ripple currents and peak currents.

3. Non-polarized design, it can sustains long-term reverse pulse voltage endurance.

4. Small dielectric loss, low equivalent series resistance(ESR), lreduced internal temperature rise, and stable temperature characteristics.

5. The capacitor is non inductive rolled, with small internal inductive ESL and fast charge and discharge speed.

6. Long service life, up to more than 100,000 hours.
