KEMET Electronics Corporation, or KEC, a wholly-owned subsidiary of the Company, and Jianghai Film Capacitor
The inverter consists of an input boost converter (one leg of the module), a film capacitor
at the DC bus, and full bridge inverter (leg two and three of the module), the outputs of which are connected to the grid through an LC filter.
Conventional electrolytic capacitor is still massively chosen, because it shows larger capacitance in the same volume and it costs much less when it is compared with novel film capacitor
. However, such electrolytic capacitor is fragile to external factors (ripple current, ambient temperature, etc.) , and its service life fluctuates seriously along with the variation of these external factors.
A film capacitor
[C.sub.SH] is connected in parallel with each of the superjunction MOSFETs to achieve zero-voltage turn-on and to minimize turn-off overvoltage across the switching devices.
Protection features include: built-in harmonic filtering DC chokes to meet EN61000-3-12 requirements, built-in EMC filter for EN61800-3 category 02, thin film capacitor
, and and integrated brake chopper.
The feedthrough capacitors contain proprietary self-healing, metallised plastic film capacitor
material, and use a solderless capacitor assembly technique to avoid heat damage.
(kemet.com), a manufacturer of capacitors for everything from industrial lighting to the International Space Station, has opened a $34-million, 52,000 ft2 power film capacitor
production facility in the lower level of its Simpsonville, SC, offices to build electrical components for hybrid and electric vehicles (EVs).
To reduce the lead resistance in capacitance structure without suffering the value of C, a new type film capacitor
is introduced--interdigital capacitor.
To smooth the output current and voltage, a 0.22 [micro]F film capacitor
is added across the output of the half-bridge rectifier; it is also needed for a sufficient charge reservoir to supply the gate.
Also, fabrication of the thin film capacitor
material and its subsequent electrical performance are described.
Northvale, NJ, January 12, 2019 --(PR.com)-- New Yorker Electronics has announced it will be distributing the new Cornell Dubilier series of DC link polypropylene film capacitor
modules for high-power inverter applications.
