A comparative study of sliding-mode control schemes for quantum series resonant inverters

This paper presents a comparative study of sliding-mode control schemes for quantum series resonant inverters. The single-input and two-input resonant systems considered in this study are designed with identical specifications. The control performance is evaluated in aspects such as load transient response, sensitivity to disturbances, and efficiency. Other aspects such as control complexity and cost are also considered. Simulation and experimental results are reported in order to validate the theoretical predictions. Essentially, the study demonstrates the following: 1) The load transient response of the proposed two-input system is insensitive to load variations; 2) the single-input system exhibits higher efficiency, particularly at light load conditions, and 3) both control schemes have similar complexity and cost.
