High energy, reliable and volumetric efficient inverters are essential to reducing emissions of vehicles based on 48 V technology. DC-link capacitors can significantly contribute to this target by reducing parasitic losses and increasing thermal efficiency. High inverter powers can be theoretically achieved with multiple capacitor connections. However, a high number of parallel-connected parts also increase the complexity of the system stability. In the field of Aluminum Electrolytic Capacitors, the Hybrid Polymer technology offers higher ripple current densities by a factor of, e.g., 5x compared to standard Liquid Electrolyte technology. By applying the Hybrid Polymer technology to the large axial capacitor can sizes, with solid mechanical construction and special thermal dissipation feature, a compact DC-link solution with a reduced amount of capacitor and minimized thermal escalation risk through stable and efficient thermal design can be achieved.

TDK Corporation (TSE:6762) presents a new series of EPCOS MKP-Y2 capacitors for interference suppression. In contrast to conventional models designed for a maximum operating temperature of 110 °C, the new capacitors offer a maximum permissible operating temperature of 125 °C. The B3202*H/J series’ capacitance ranges from 1 nF to 1 µF with a maximum rated voltage of 300 V AC. The capacitors are certified according to IEC 60384-14:2013/AMD1:2016 and approved according to AEC-Q200D, UL, and EN. Depending on the capacitance, the products are available in lead spacing of 10 mm (B32021H/J*), 15 mm (B32022H/J*), 22.5 mm (B32023H/J*), and 27.5 mm (B32024H/J*) and 37.5 mm (B32026H/J). The housing, for example potting material, corresponds to UL94V-0.

In the automotive field, CPUs and FPGAs for systems that require advanced image processing, such as onboard ADAS ECUs and autonomous ECUs, need to operate at high speed and require high drive current in conjunction with the increasing performance and functionality of systems. Also, in the ICT field, power supply configurations that support higher current required for devices that need huge amounts of power such as servers. There is a trend towards higher operating speeds and higher currents in the power supply lines of systems with increased performance and functions as described above. At the same time, power supply structures that maintain the nominal voltage within narrow tolerance ranges, which have decreased in conjunction with processor miniaturization, are also required.
