Webinar: Sustaining high-temperature DC-link film for 800V+ SiC Inverters

Advanced Conversion is addressing a critical challenge in the development of 800V+ silicon carbide (SiC) inverters by introducing Peak Nano’s NanoPlex™ LDF, a high-temperature dielectric film designed to meet the demanding conditions of DC-link capacitors. Traditional dielectric films have struggled to cope with the thermal, voltage, and dV/dt stresses inherent in these high-voltage applications, and the recent exit of a key high-temperature film supplier has created a supply gap in the industry. NanoPlex LDF offers a domestically manufactured alternative that maintains compatibility with Advanced Conversion’s patented Power Ring platform, ensuring seamless integration without necessitating redesigns of existing inverter systems. The webinar scheduled for 17 June 2026 will provide an in-depth technical exploration of the dielectric properties essential for 800V+ SiC DC-link applications and how NanoPlex LDF meets these criteria. Attendees will gain insight into the material’s performance envelope and the ongoing characterisation programme funded by Peak Nano, which aims to validate and potentially extend the capabilities of this new film beyond the established PEN HV baseline. The session promises a detailed discussion on the film’s integration into the Power Ring architecture, highlighting its ability to withstand the rigorous electrical and thermal demands without compromising system reliability. Industry stakeholders have expressed interest in the implications of securing a domestic supply chain for these advanced dielectric films, particularly for multi-year inverter programmes where consistency and availability are paramount. By closing the supply gap, NanoPlex LDF not only supports the continued advancement of high-voltage SiC inverter technology but also mitigates risks associated with overseas dependency. The webinar will also address open technical questions and outline the roadmap for further testing, signalling ongoing innovation and refinement in this critical component of electric power electronics. Overall, this development represents a significant step forward in sustaining high-performance DC-link capacitors for next-generation electric vehicle and renewable energy applications. The combination of Advanced Conversion’s Power Ring platform and Peak Nano’s NanoPlex LDF film underscores the importance of material science innovation in overcoming current limitations and ensuring the reliability of 800V+ SiC inverter systems. As the industry moves towards higher voltages and greater efficiency, solutions like these will be vital in supporting the broader adoption of electric motorsport and cycling technologies.
