This paper presents a novel concept of a DC-AC converter that ensures AC voltage modulation on four levels using a single branch and achieves voltage boosting. The proposed boost inverter is based on a single-stage topology and does not use a DC-DC b

The paper presents efficiency and power loss analysis in a high-frequency, seven-level diode-clamped inverter (7LDCB). The inverter is composed of four-level (4L) diode-clamped branches based on MOSFET transistors and Si Schottky diodes. The range of

This article presents the results of research on a new topology of a DC-DC converter in which switching losses are reduced by an auxiliary switching circuit (ASC). The proposed ASC can work as a passive or active circuit depending on the voltage gain
