【 摘 要 】

Based on the topology of diode clamped three-level inverter, this paper introduces the working principle and control method of the inverter. This paper focuses on the midpoint potential balance problem and PWM control method of Diode-clamped three-level inverter and the SVPWM control method developed thereby. In this paper, the analysis of inverter topology and control method is focused on the maximum power point tracking problem and phase-locked loop problem in photovoltaic grid-connected process. This paper proposes a complete system for photovoltaic grid connection using inverters. At the end of this paper, the results of simulation and analysis of the system using computer software are given.
