摘要
Abstract
This paper presents a new three-level grid-connected photovoltaic inverter circuit based on RB-IGBT, analyzes its switching losses and conduction losses with different switching frequency, introduces the method of the relevant losses calculated by MATLAB software, compares with the NPC three-level inverter circuit and two-level inverter circuit losses running in the same circumstances,thus,obtains the conclusion what this inverter circuit used in the grid-connected photovoltaic inverter can improve the efficiency.关键词
