proposed. The power conversion concept is based on a bidirectional flyback converter with …

The Class/EF amplifier is an attractive topology for high-voltage and high-frequency power
conversion because of the high efficiency, reduced device voltage stress, simplicity of gate …

This article provides a systematic survey on the topology morphing control techniques used
in the galvanically isolated dc-dc converters. Existing techniques are broadly categorized …

In this article, we propose a topology simplification method (TSM) for power converters,
based on graph theory, to improve the converter design. In the proposed method, a directed …

This article proposes a time-step-adaptive filter discretization method for variable sampling
frequency (VSF) control considering the effect of the previous sampling time steps on the …
