Performance of the Resonant Converters under the Self-sustained Oscillation Based Control Techniques

This paper presents the performance merits of the self-sustained controllers used in resonant power supplies. They are namely; self-sustained oscillation controller (SSOC), and self-sustained phase shift modulation (SSPSM). The paper contrasts these controllers to the variable frequency controller (VF). The comparison is done via connecting each of them to a study case of a full bridge series resonant converter. The paper records the semiconductor stress, conduction loss, zero voltage switching (ZVS) capability, switching frequency range, and transient response of the converter under each controller. Mathematical expressions, simulation results, experimental results, and concluding tables are given to quantify the capabilities and shortfalls of each control technique
