DTU's CELCORR develops simulation apps to prevent high-voltage electronics failures from humidity

Rising Demand for High-Voltage Electronics

The demand for high-voltage electronics is increasing due to advancements in electric vehicles, which require improved range, greater reliability, and faster charging. Other sectors driving this demand include wind farms, data centers, and server farms. As the use of these electronics expands, the risks associated with their sudden failure become a critical concern.

Humidity as a Root Cause of Failure

A significant cause of high-voltage equipment malfunction is environmental conditions, particularly humidity. Condensation on electronic surfaces can lead to corrosion, which in turn causes issues such as stray leak current and dendrite shorting during Electrochemical Migration (ECM). This corrosion can result in unexpected functional problems and, in high-voltage applications, even fire hazards.

DTU's CELCORR Addresses Corrosion

The Centre for Electronic Corrosion (CELCORR) research group at the Technical University of Denmark (DTU) is focused on predicting, mitigating, and designing against corrosion. Researchers at CELCORR are collaborating with industry partners to develop models and simulation applications. These tools are intended to aid in building robust electronics designs that can withstand humid operating conditions, thereby preventing failures in critical applications.

Impact on Energy Systems

Automotive electrification and renewable energy systems heavily rely on electronics throughout their energy chains. According to Dr. Rajan Ambat, DTU professor and manager of CELCORR, ambient moisture can infiltrate devices and machines, causing corrosion and unexpected functional issues. Understanding how condensation forms and leads to system failure is crucial for manufacturing reliable electronics, especially in high-humidity environments.
