Three-Mode Variable-Frequency Modulation for the Four-Switch Buck-Boost Converter
A QR-BCM Versus TCM Case Study and Implementation
Quasi-resonant boundary-conduction mode (QR-BCM) and triangular current mode (TCM) have found widespread use in the literature and industry due to their good performance at relatively low complexity. However, additional control challenges occur when these modulations are applied

The impact of V2X on battery degradation
A quantitative review
Vehicle-to-Everything (V2X) is a promising solution to support the energy transition, but concerns about battery degradation and capacity loss remain a major barrier for electric vehicle (EV) users. A clear understanding of degradation caused by V2X is essential to increase user
