TDK-EPC has presented a new series of MKP AC capacitors with a capacitance range from 2 to 75 μF and radial terminals for PCB mounting.
The B3279* series of output filter capacitors features types for voltages up to 400 V a.c. and can be used in a wide range of output filter modules. Higher capacitance values can be realised by placing several capacitors in parallel in the PCB assembly, thus allowing filter designers and manufacturers to design power converters even up to 500 kW with modular systems.
Power electronic designers are implementing more and more complex switching algorithms for pulse-width modulation (PWM) to gain efficiency and power quality. Such designs, however, introduce higher frequencies and harmonics into systems, which must be properly filtered by using LC and LCL filters at the output of the frequency converters. Applications for the new series are, in particular, in star-connected LCL circuits of three-phase power converters (DC/AC or AC/AC) for drives. Further applications include inverters for solar power as well as UPS systems and discrete filters. The capacitors can also be used in single-phase systems.
