    This paper discusses different measurement
    methods to evaluate the efficiency of WBG-based
    power supply solutions, including electrical
    measurement methods and their verification with
    calorimetric methods, and compares the
    performance of Si-based and GaN-based
    chargers. The efficiency of chargers was
    measured at different load conditions, and it was
    observed that the maximum efficiency occurred
    generally at higher powers. GaN-based solutions
    outperformed Si-based chargers at higher power
    levels, leading to significant energy savings. The
    paper suggests that regulations for efficiency can
    be tighten and different voltage modes shall be
    included to ensure further energy savings. The
    benefits of using WBG devices are more evident
    in terms of power density, which could lead to
    their wider adoption in other power electronic
