High-Accuracy Generalized Average Model of Dual Active Bridge Converters

This article presents a detailed procedure for deriving the generalized average model (GAM) of a dual active bridge converter. The proposed model incorporates higher orders of harmonic components to increase accuracy. Moreover, the turn ratio of the high-frequency transformer (N_t) is considered for realistic modeling, which removes the...

Charging Infrastructure and Grid Integration for Electromobility

Electric vehicle (EV) charging infrastructure will play a critical role in decarbonization during the next decades, energizing a large share of the transportation sector. This will further increase the enabling role of power electronics converters as an energy transition technology in the widespread adoption of clean energy sources and their...

Adaptive Modularity for Power Electronics Based Electrolysis Systems for Green Hydrogen

Electrolysis holds tremendous potential in reducing the carbon footprint and providing energy dense fuels such as methane. Such systems can be integrated with renewable energy systems with the aid of power electronics interfaces.

Inductive Power Transfer based on Variable Compensation Capacitance to Achieve an EV Charging Profile with Constant Optimum Load

Wireless charging must be highly efficient throughout the entire battery charging profile to compete in the electric vehicle (EV) industry. Thus, optimum load matching is commonly used: it operates at the equivalent load that maximizes the efficiency, which depends on the coil's alignment. In this article, the optimum load is made independent...
