In electric vehicles, the high-voltage (HV) harness functions similarly to an aorta, connecting various components within the HV electrical system. It must withstand high voltages of 600V or more to ensure reliable performance and prevent insulation failures at elevated temperatures. MICROTEST provides an integrated solution combining HV and low-voltage (LV) electrical testing systems, featuring up to 128 test channels. This setup allows for efficient quality control of high-voltage harnesses, supporting advancements in new energy technologies.

In applications involving electrical energy storage and conversion, dielectric capacitors utilize dielectric storage technology. As new energy vehicles continue to develop rapidly, DC bus capacitors integrated with IGBT modules have become crucial components in highly efficient motor-controlled inverters.

Polymer film capacitors and electrolytic capacitors are the most commonly used DC bus capacitors in new energy vehicles. Enhancing capacitor performance requires materials with a high dielectric constant and low dielectric loss, which applies to both the conductive electrolyte materials and the polymer dielectric materials used in their construction.
