EPCOS Introduces Compact AC Film Capacitors

EPCOS has introduced a new series of EPCOS MKP AC capacitors with a capacitance range of 2 to 75 μF and a radial termination for PCB mounting. Output Filter Capacitor The B3279* series is available in models up to 400 V AC for a range of output filter modules. Higher capacitance can also be achieved by connecting several capacitors in parallel in the PCB assembly, allowing filter designers and manufacturers to design up to 500 kW power converters in a modular system. Compared to other AC filtering solutions, the B3279* series offers higher capacitance values ​​in smaller sizes, higher current densities in fixed capacitance and volume conditions, and operation at 105oC.

At present, in order to obtain high efficiency and power quality, many high-power electronic equipment designers begin to use more and more complicated switching algorithms when performing pulse width modulation (PWM), and similar designs will bring higher frequency harmony to the system. Waves, which require proper filtering at the output of the frequency converter using LC and LCL filters. The new series can be used as a drive for star-connected LCL circuits in particular for three-phase power converters (DC/AC or AC/AC). It can also be used for solar inverters as well as UPS systems and discrete filters. This series of capacitors can also be used for single-phase systems.

The B3279* series extends the existing capacitor (X2305 V AC) B3292*E/F series, which is used for input AC filters and discrete EMC filters.
