Computer-Aided Identification of Equivalent Power Electronics Converters
Published in TPE, 2019
Equivalent power electronics converters (PECs), which have same performance characteristics but dissimilar configurations, are easily mistaken as different converters to be repeatedly studied in the practice, resulting in extra workload. Therefore, it is essential to implement the equivalence identification to avoid the undesired repeated research. In order to accomplish this goal, a computer-aided solution is proposed in this letter, aiming to quickly and precisely identify the equivalent PECs. Download paper here

Graph Theory-Based Programmable Topology Derivation of Multiport DC–DC Converters With Reduced Switches
Published in TIE, 2022
Different from the typical topology derivation of power electronics converters (PECs) depending on manual effort, this article aims to explore a programmable method based on graph theory for multiport dc–dc converters with reduced switches. By mathematically modeling converters with graph theory and transforming their working criteria into the corresponding graph constraints, the topology derivation can be automatically and conveniently solved with the aid of computer program.

Computer-Aided Systematic Topology Derivation of Single-Inductor Multi-Input Multi-Output Converters From Working Principle
Published in TCAS-I, 2022
In this paper, aiming to systematically derive single-inductor multi-input multi-output (SI-MIMO) converters having favorable merits of high-density and low-cost, a basic model is firstly extracted from the working principle. Theoretically, by enumerating all possible connections of the basic model and one-by-one manually judging their effectiveness according to working criterions, multiple viable SI-MIMO topologies can be obtained, but with heavy workload. To simplify the topology derivation process, this paper also proposes a computer-aided method to replace the manual effort. By modelling the basic model and working criterions with graph theory, MATLAB codes can be developed to automatically screen out the effective topologies. With the proposed method, 8 three-port, 28 four-port and 115 five-port converters with single inductor are conveniently obtained, including both the existing and new topologies. Moreover, by configuring ports and switches in each derived topology, multiple specific converters can be further expanded. These converters can provide more options for practical engineering applications, and a new topology is also introduced and experimentally verified in the paper. Download paper here

A Wide Input Voltage Range Switched-Capacitor Multilevel Inverter Based on Adjustable Number of Output Levels
Published in TPE, 2023
This paper presents a wide input voltage range switched-capacitor multilevel inverter (SCMLI) based on an adjustable number of output levels. Through different modulation strategies, the number of output levels in the inverter has five possibilities, including 9, 11, 13, 15, and 17 levels. Therefore, when the input voltage varies, the inverter can correspondingly adjust the number of output levels to remain the sinusoidal output voltage constant. In this paper, the modulation strategies and operation principle of the inverter under all the possible numbers of output levels are analyzed in detail. Subsequently, a prototype of the inverter is designed and the experimental results with different input voltages are also provided to validate the inverter effectiveness. Download paper here
