Autoencoder-Based Sensor Drift Detection and Mitigation for Resilient Charging Systems
This work presents an autoencoder-based approach for sensor signal reconstruction and drift detection for charging systems. The proposed strategy is implemented within a Simulink-based system framework and evaluated under multiple operating conditions. An autoencoder with 8 neurons in the bottleneck layer is adopted, achieving accurate reconstruction across 10 variables an…

Understanding middle-point inductance’s effect on switching transients for multi-chip SiC package design with P-cell/N-cell concept
Middle-point inductance L_middle can be introduced in power module designs with P-cell/N-cell concept. In this paper, the effect of middle-point inductance on switching transients is analyzed first using frequency domain analysis. Then a dedicated multiple-chips power module is fabricated with the capability of varying L_middle, and extensive switching tests are conducted…

50-kW 1kV DC bus air-cooled inverter with 1.7 kV SiC MOSFETs and 3D-printed novel power module packaging structure for grid applications
The traditional heatsink design technologies for forced air-cooling and power semiconductors with low junction temperatures have constrained the converters to be designed with massive heatsinks. The low power losses of WBG device technology and higher junction temperature operation over a wide operating range of power have not been fully utilized with liquid-cooled systems…

Dynamic Boundary Microgrids Under Privatization Considerations
Microgrids have physical, electrical, and logical (data, network, and ownership) boundaries. To power unserved customer loads during an outage, microgrids can extend the traditional operational boundaries. This can become complex when considering microgrid-to-microgrid (M2M) interactions where sensitive information such as competitive microgrid operational data is not shar…

A study on dc fault handling of dc-dc converter based on series and parallel connected DABs in MVdc applications
With the increase of direct current (dc) based power generating stations and loads, multi-terminal medium voltage dc (MT-MVdc) systems are gaining popularity. The dc sources and loads are interfaced with the MT-MVdc systems using series and parallel connected dual-active-bridge (SP-DAB). In this paper, the dc fault ride through procedure of SP-DAB meant for MT-MVdc applica…
