The B3279* series of output filter capacitors features voltage ratings up to 400 VAC and can be used in a wide range of output filter modules. Higher capacitance values can be achieved by placing multiple capacitors in parallel on the PCB, allowing filter designers and manufacturers to design power converters, even up to 500 kW, using modular systems. Operating temperatures reach up to 105°C.
Power electronics designers are increasingly implementing more complex switching algorithms for pulse-width modulation (PWM) to improve efficiency, quality, and power output. However, these designs introduce higher frequencies and harmonics into the systems, which must be filtered using LC and LCL filters at the output of the frequency converters. The primary applications of the new series are, in particular, in star-connected LCL circuits of three-phase power converters (DC/AC or AC/AC). Other applications include solar power inverters, UPS systems, and discrete filters. These capacitors can also be used in single-phase systems.
