Abstract

With the fast development of high-temperature metal oxide semiconductor field effect transistors for power electronics in electric vehicles, current state-of-the-art biaxially oriented polypropylene (BOPP) film capacitors need further improvement because they have a temperature rating of only 85 °C without derating the voltage to maintain a long lifetime. If a high-temperature polymer can replace BOPP without sacrificing the overall dielectric performance and cost, it is possible to remove the current water-cooling system for capacitors and significantly reduce the cost of the power electronic unit. In this work, we demonstrated new polycarbonate (PC)/nylon multilayer films (MLFs), which has a potential for even higher temperature rating because of the higher melting temperature for nylons (e.g., nylon-6). Structural and dielectric studies showed that these PC/nylon MLFs had a similar dielectric performance, such as dielectric constant, dielectric loss, and breakdown strength, as the PC/poly(vinylidene fluoride) PVDF MLFs, which were developed in the past. These PC/nylon MLFs could perform well up to 120 °C, which was limited by the glass transition temperature of PC at 145 °C. Here, more intriguingly, packaged PC/nylon-12 MLF capacitors exhibited a self-healing capability, which had been difficult for packaged high-temperature film capacitors. Because self-healing is such a fundamental requirement formore »« less

Enhanced dielectric properties due to space charge-induced interfacial polarization in multilayer polymer films

Journal Article Chen, Xinyue ; Tseng, Jung-Kai ; Treufeld, Imre ; ... - Journal of Materials Chemistry C

We report that with the recent advancement of power electronics, polymer film capacitors have become increasingly important. However, the low temperature rating (up to 85 °C) and low energy density (5 J cm ^-3 at breakdown) of state-of-the-art biaxially oriented polypropylene (BOPP) films have been limiting factors for advanced power electronics. Based on our recent work, multilayer films (MLFs), which consist of a high energy density polymer [e.g., poly(vinylidene fluoride) (PVDF)] and a high breakdown/low loss polymer [e.g., polycarbonate (PC)], have shown potential to achieve high energy density (13–17 J cm ^-3), enhanced breakdown strength, high temperature tolerance, and lowmore »« less

Multilayered Film Capacitors for Advanced Power Electronics and Electric Motors for Electric Traction Drives

Technical Report Langhe, Deepak ; Zhu, Lei ; Brubaker, Michael ; ...

Biaxially oriented polypropylene (BOPP) film capacitors are the most suitable technology for high voltage, high temperature, and high ripple current power electronic systems in high performance electric vehicles (EVs). These capacitors, however, occupy 1/4th to 1/3rd of the power electronic unit and have a 50% voltage derating above 85 °C due to their drastically deteriorated breakdown strength and lifetime at high temperature. Development of a new dielectric material system for capacitors to increase temperature use and reduce size is critical in many EV related applications. Multilayer dielectric film developed by PolymerPlus and team has demonstrated improved dielectric constant and breakdownmore »« less

Reducing dielectric loss and enhancing electrical insulation for multilayer polymer films by nanoconfined ion transport under high poling electric fields

Journal Article Chen, Xinyue ; Allahyarov, Elshad ; Langhe, Deepak ; ... - Journal of Materials Chemistry C

High temperature polar polymers have demonstrated potential for good thermal stability and high dielectric constant at the same time. However, polarization of contaminated impurity ions in polar polymers, even at the ppm level, can significantly increase the dielectric loss at high temperature and low frequencies. One effective strategy to mitigate this problem is to multilayer them with a high temperature nonpolar dielectric polymer to confine impurity ion transport at the nanometer scale. In this study, confined ion transport in high temperature polycarbonate (HTPC)/poly(vinylidene fluoride) (PVDF) multilayer films under high AC electric fields was studied using a direct analytical simulation method.more »« less

High Temperature DC Bus Capacitor Cost Reduction & Performance Improvements

Technical Report Yializis, Angelo ; Taylor, Ralph S.

The goal of this DOE program is to develop high temperature, high energy density, lower cost DC- Link capacitors, for inverters used in electric drive vehicles. Most electric motors in Hybrid Electric Vehicles (“HEVs”), Plug-in Hybrid Vehicles (“PHVs”) and Electric Vehicles (“EVs”) are driven with variable AC voltage supplied by an inverter/converter power module that converts the DC battery voltage to three-phase AC voltage. A key component of the inverter circuit is the DC- Link capacitor used to minimize ripple current, voltage fluctuation, and transient suppression. The DC-Link capacitor is one of the largest, costliest, and most failure-prone components inmore »« less
Performance of electric double layer capacitors with polymer gel electrolytes

Conference Ishikawa, Masashi ; Kishino, Takahiro ; Katada, Naoji ; ...

Polymer gel electrolytes consisting of poly(vinylidene fluoride) (PVdF), tetraethylammonium tetrafluoroborate (TEABF{sub 4}), and propylene carbonate (PC) as a plasticizer have been investigated for electric double layer capacitors. The PVdF gel electrolytes showed high ionic conductivity (ca. 6 mS/cm at 298 K). To assemble model capacitors with the PVdF gel electrolytes and activated carbon fiber cloth electrodes, a pair of the fixed electrodes was soaked in a precursor solution containing PC, PVdF, and TEABF{sub 4}, followed by evaporation of the PC solvent in a vacuum oven. The resulting gel electrolytes were in good contact with the electrodes. The model capacitors withmore »« less
