This paper proposes a Pyramid-Type (PT) topology for multilevel power converters. The phase-leg of a PT-structure is comprised of half-bridge modules, as the main power electronics building blocks (PEBBs), that are connected in a pyramid form. The proposed PT-arrangement is primarily used to interconnect and tie the distinct and/or same types of 2-level and/or multilevel inverters together. The PEBBs are realized by the soft-switching low-frequency semiconductor devices such that the two switches of each half-bridge module turn on concurrently during voltage-level transitions. This is achieved through elimination of switching dead-time, and including an overlap into gate signals. This results in zero-voltage-switching (ZVS) or zero-current-switching (ZCS) phenomena for switches within the PEBBs. The utilization of PT-topology for interconnection of converters leads to new configurations. This paper reviews the PT-based derived topologies, and explores the advantages. For instance, a 3-level inverter topology, as the simplest structure, is investigated in this paper. The PT-topology is verified using the experimental results obtained from the prototype of a 3-level inverter formed by interconnection of two 2-level inverters via one PEBB.
