Spatiotemporal Measurement of Charge at Ceramic Substrate-Silicone Gel Interface in Medium-Voltage Power Modules

With the proliferation of high-voltage, high-power density devices, insulation failure has emerged as a latent hazard in power modules. Notably, breakdown along ceramic substrate-silicone gel interfaces is a typical insulation failure process in power modules, necessitating particular attention and...
