Research on the Three-Level Inverter Midpoint Potential Algorithm Based on the Charge Balance Theory

Abstract:

In order to achieve high voltage, high-power,two-level inverter need to switch in series which results switch static, dynamic-pressure problems. Three-level inverter solve this problem for its circuit, but this circuit has the midpoint potential imbalances of the DC side, we propose to charge balance theory based on the three-level inverter midpoint potential algorithm to solve the problem, build simulation model to validate the algorithm on the midpoint potential in MATLAB.
