PK16™ Series系列

The PK16™ capacitor can be universally used for the assembly of low inductance DC buffer circuits and DC filters; with its high energy density it can replace banks of series-connected electrolytic capacitors as well as large film capacitors in rectangular cases.

The capacitance in a DC buffer circuit must be sufficiently sized to both handle and smoothen the occurring ripple currents.

The traditional use of series-/parallel-connected electrolytic capacitors offered large capacitance at seemingly low cost, however the low cost per microfarad is countered by the very low current strengh, the high sensitivity to voltage and current surges, as well as a substantial risk of failures in the field, resulting in high maintenance cost.

Our advanced know-how in special capacitor film coating（Patent No.DE4142855A1，DE102019100071A1) and many years of practical experience in designing and manufacturing capacitors have allowed us to develop our PK16™ range with high capacitance density. With fivefold the current strength of conventional electrolytic capacitors, it is not necessary to provide the same capacitance in film technology to handle a given current.

Instead, the user now gets a superior technical solution within the same - or even less - space, offering:

· superior voltage and current strength

· dramatic increase in operational life

· drastic reduction of failures

· minimization of power dissipation losses

· substantial reduction of self-inductance and series resistance

· more exact manufacturing tolerances

· elimination of sharing resistors

Thanks to its compact cylindrical design this capacitor is ideal for both the electrical and mechanical requirements of high-speed IGBT converters.

Its robust terminals and the robust fixing stud allow for very simple, reliable mounting and connection that unites lowest inductance and supreme current strength.

The particularly large clearance and creepage distances make this design suitable for a wide range of operating voltages. As a result, existing standard converter concepts can easily be adapted to new applications without having to change the principal construction and to re-approve the entire system.

PK16™ 电容可普遍用于组装低电感直流缓冲电路和直流滤波器。凭借高的能量密度，它可以替代串联的电解电容器组和矩形外壳的大型薄膜电容。

直流缓冲电路中的电容，容量必须足够大，以处理和平滑出现的纹波电流。

传统使用串联或并联连接的电解电容器组提供大容量，看似成本低，但与每微法的低成本相对应的是，非常低的电流强度、对电压和电流浪涌的高度敏感性、以及很高的现场故障率带来的巨大风险和高昂的维护成本。

我们在特殊电容薄膜蒸镀方面先进的专有技术(专利号： DE4142855A1，DE102019100071A1)，以及在电容器设计和制造方面的多年经验，使我们能够开发出具有高容量密度的PK16™系列电容。由于其电流强度是传统电解电容器的五倍，因此无需在薄膜技术中以相同的容量来处理给定的电流。

相反，我们的用户可以在相同或更小的空间内获得卓越的技术解决方案：

· 优越的电压和电流强度

· 大幅提高运行寿命

· 大幅减少故障率

· 功率耗散损耗达到更小

· 大幅降低自感和串联电阻

· 制造公差更精确

· 消除共享电阻

紧凑的圆柱形设计，使该电容器非常适合高速IGBT变流器的电气和机械要求。

坚固的端子和固定螺栓，确保简单、可靠的安装和连接。最低的电感与最高的电流强度合二为一。

超大的电气间隙和爬电距离，使其设计可以覆盖宽广的运行电压范围。因此，现有的标准变流器方案可以轻松适应新的应用，而无需更改主要结构和进行新的系统测试。
