Research Based on SVPWM Method of Three Level Inverter

摘要：

This paper focuses on method of three-level inverter.A system of three-level Space-Vector PWM (SVPWM)based on one chip DSP and CPLD is proposed.Neutral-point balance is achieved by adjusting the output voltage vectors based on the neutral-point current judging.This method simplify the digital control of three-level inverters and improved the reliability of system.The paper mainly focuses on the control system of diode-clamped three-level inverter and introduces a method that realizes the generation of three-level inverter space vector with the combination of DSP and CPLD.This method can control the neutral point voltage balance and limit the output voltage du/dt.The experiment results verify this method is feasible.The DSP solution offers sophisticated control schemes with very good performance.A full digital control method based on the SVPWM is developed in this paper.
