Abstract
PWM frequency converter is one of the important tools in modern industry, which plays an important role in solving the production and application problems. However, the high voltage common mode voltage generated by it has certain restrictions on the use of PWM frequency converter. Based on this, this paper proposes the research on the output common mode voltage suppression technology of PWM frequency converter. First, the SPWM modulation uses the equivalent signal to replace the sine wave signal, and then the common mode voltage generated by SPWM is analyzed for data, explain the causes of the common mode voltage from the theoretical data, clarify the characteristics of the PWM inverter, analyze the influencing factors of the common mode voltage, and design the suppression method according to the influencing factors. Finally, the feasibility and correctness of the suppression method are verified through simulation experiments. In order to provide a new idea and method for the related research of the output common mode voltage suppression technology of PWM inverter.
