Advanced power film capacitors with controlled self-healing technology are one of the power electronics solutions that EV and HEV engineers can rely on to meet the stringent size, weight, performance, and zero-catastrophic-failure reliability criteria of this demanding market.
Power film capacitors capable of delivering reliable design solutions for EVs and HEVs must meet several specific parameters regarding metalized film materials, processing, and design.
Feature
Sustainable development has become a critical and ubiquitous concept in the contemporary era. Specifically, in the energy industry, clean, renewable energy solutions are replacing traditional oil-based methods. With EV and HEV being the rising market, inverters are required to have smaller size, higher energy density, wide bandgap (WGB) and zero-catastrophic-failure in order to substitute traditional internal combustion engine (ICE). As a result, metalized film capacitor is an indispensable prerequisite for future EV and HEV to satisfy these market criteria.
Metalized film capacitor at CRE has the feature of self-healing, a capability to prevent catastrophic failure when an internal defect occurs. The dielectric film in our capacitor is coated with metallic material which is vacuum-deposited and has a thickness of only dozens of nanometers. When there is a weak point or impurity on the dielectric, a breakdown will occur. The energy released by the arc discharge at the breakdown will be sufficient enough to evaporate the metal layer around, isolate the defect and effectively heal the capacitor to maintain functionality.
With this self-healing technology, our metalized film capacitors are applicable for a wide range of market demand and capable to fulfill advanced electronic requirements including those of inverters used in EV and HEV. They possess a long life-expectancy and practical reliability with zero catastrophic failure. In addition to the advantages resulted from the self-healing feature, our capacitors are also small in size with large capacitance. They could be easily installed and could resist high voltage.
The metalized film capacitors is applied by CRE patent designs. They are usually infused with dry resin, wound by Myra tape and sealed by either metal or plastic shell. The patent design will bring various advantages including balancing current and inductance, no critical thermal expansion, high electrical field and lower production cost. Multiple capacitor bobbin could be soldered into a bus bar structure to offer lower self-inductance values which could be used to limit over-voltage during switching.
As one of the responses for clean energy trend and sustainable development, the EV and HEV market is expected to continuously expand and eventually replace ICE models. Metalized film capacitors at Wuxi CRE will be the effective, reliable and leading solution for your future production.
