GDHY C53 DC link film capacitor metallized polypropylene film capacitors high voltage capacitor

Metallized film capacitors use the polypropylene film dielectric vacuum steaming metallized electrode, made by automatic cutting and winding equipment, application of non-inductive winding technology, internal adopts copper core inverter spot welding connection, special spray gold craft, resistance is molded case shell encapsulation, epoxy potting, heavy copper nut, tin copper wire or end plate derivation, makes the capacitor has big power, high temperature resistant, long service life, use safety, the effect series resistance is small, small self-inductance, over current, over voltage ability, can withstand large ripple current and has the characteristics of self-healing.Box-type, Copper nut/screw leads, insulated plastic cover positioning, easy installation. Large capacity,small size.Resistance to high voltage, with self-healing. High ripple current, high ripple current, high DV/DT withstand capability.DC link capacitors are widely used in dc-link circuits for filtering and energy storage, frequency converter, inverter, and inverter power supplies.                                                                                                                                   

Excellent features of DC-Link film capacitors are as follows: high stability, long service life. Non inductive structure. Excellent self-healing performance. The equivalent series resistance is small. Strong over current and over voltage ability. Small loss, can carry large ripple current. High insulation resistance, low dissipation, good self-healing character, anti-striking current, strong over-carrier capacity and steady electric performance.                                                                                                 
The DC-link capacitor must balance fluctuating instantaneous power on the rails injected by activity from the first and third stages. The polypropylene film capacitor stabilizes the “ripple” generated by Stage III’s high-frequency power switching circuits. Ripple current/voltage (specified at a given frequency and temperature) is the total amount of Root Mean Square (RMS) alternating and direct current/voltage that a capacitor can withstand without failing. The DC-Link capacitor (located in Stage II) must stabilize and smooth out the voltage and current on the rails (i.e., decoupling spikes caused by switching).
