Enhanced Selection of Ceramic Capacitors

NY3 Series Ceramic Capacitor

Ceramic capacitors are used in a variety of applications such as high voltage power supplies, filtering, coupling and decoupling, timing, voltage multipliers and by-pass circuits. The ceramic capacitor voltage ratings are high for their size and offer a selection of dielectrics contributing to high stability or high permittivity.

PPM Power has expanded its range of Ceramic Capacitors from Dean Technologies to now encompass 11 Series divided into two application classes and four form factors.

Class I offer high stability voltage and temperature coefficients with low capacitance loss for resonant circuit applications.

Class II offer high volumetric efficiency, where only a minimum value of capacitance is required such as buffering, by-pass and coupling applications.

The stability of the capacitor is dependent on the ceramic dielectric.

As different dielectrics give the capacitors very different properties, choosing the specific type of dielectric is an important consideration, for example, NP0 is the best for high voltage, low temperature coefficients and stability.  BxN however, has 5% variation over the temperature range and only 2.5% loss on voltage.

Best DC Link Capacitor? Power Ring from Advanced Conversion

Power ring vs. conventional capacitor temperature graph
Advanced Conversion’s Power Ring capacitors have a high performance design that reduces losses and inductance, while increasing the ripple current rating compared to traditional film capacitor technology. The ring shape construction enables extremely low internal losses (ESR) and minimises the inductive properties (ESL). For example, a 1000 µF – 600 V DC link exhibits ESR values as low as 0.15 mΩ. This performance makes the Power Ring capacitors one of the best DC link capacitors on the market.

Power Ring, the best DC link capacitor  Advanced Conversion best DC link capacitor graph form factor

How good is the thermal performance of a Power Ring?

The graph of temperature versus ripple current below illustrates the huge improvement in thermal performance delivered by the Power Ring design versus a conventional array of film capacitors. This performance improvement translates to a more efficient use of microfarads where high ripple current is an issue. Rather than adding capacitance until the capacitor bank can handle current to achieve the required life (which would result in increased cost and size), the design can be optimised for current handling instead.

Power ring vs. conventional capacitor temperature graph

Advanced Conversion can provide solutions using PEN HV film, which allows for higher operating temperatures up to 125 ⁰C.

The DC link capacitors are also designed with solid insulation, solving creepage and clearance issues typically found in high altitude and high voltage applications.

Using the Power Ring for a snubberless circuit design

A Power Ring DC link capacitor with integrated bus bar offers a loop inductance that can allow for a snubberless circuit design in some applications. Snubber capacitors get very hot since they are connected to the IGBT pins (often the hottest point other than under the die itself) and are almost never directly cooled due to the difficulty of connecting cooling plates. Their small size and poor cooling mean snubber capacitors are usually the weak link in the reliability chain for an inverter.

As usable operating voltage increases there can be a tendency to add a snubber to get every bit of safe operating voltage out of a system. The integrated Power Ring capacitor is a more effective method of reducing overshoot, and therefore increasing safe operating voltage, without compromising reliability or system lifetime.

Integrating DC link capacitor designs

Advanced Conversion integrated capacitor and busbar assemblies can be fully customised to match customer voltage, ripple current and mechanical requirements. The design capability is very broad with our project team working closely with customers to make sure the optimum solution is delivered.

APCS custom design process

In short…

A cooler DC link capacitor means a longer lifetime. A lower ESL means reduced overshoot and undershoot, which reduces stress. Removing the requirement for a snubber capacitor means lower costs, a smaller design and a longer lifetime.

Easily Integrate HV Components with Ceramic Substrate Printing

EBG resistor capacitor circuit with ceramic substrate printing
Ceramic substrate printing is making it easier and faster to produce designs of compensated dividers or high voltage filter networks.

The fabrication of EBG resistors with extra passive components is now available to the design engineer. Custom value resistors can be printed onto the same ceramic substrates as other surface mount components.

The integration of other components with resistors on a single ceramic substrate eliminates the need to assemble multiple pieces, resulting in reduced production time and bill of materials. As an added benefit, the ceramic substrate also provides greater isolation for the resistors and other components.

Resistor Capacitor Circuit

To demonstrate the new capability, the below example shows a ceramic substrate, with resistors and surface mount capacitors. This resistor capacitor circuit was custom designed to fulfill the customer’s requirement of conserving space and simplifying manufacturing.
