Transmission over standard high-voltage alternating current (HVAC) methods that are well-established for long-distance, point-to-point power transfers are.
AC filtering film capacitors deliver extremely stable capacitance and ESR
Vishay Intertechnology now offers a new series of metallised polypropylene AC filtering film capacitors optimised for high humidity environments. The Vishay Roederstein MKP1847C AC Filtering devices withstand demanding THB testing 40C, 93% relative humidity for 56 days at rated voltage with no alteration to their electrical characteristics.
The capacitors ensure extremely stable capacitance and ESR values over an extended service life under harsh environmental conditions throughout operation. Compared to previous-generation devices, the series provides higher humidity robustness at a lower cost while keeping the same footprint. The robust devices are excellent for input and output filtering in UPS systems, renewable energy inverter grid interfaces, and welding equipment.
