报告简介：

This talk introduces two advanced control strategies aimed at enhancing the performance of three-level inverters: The first part addresses inverter nonlinearity, which mainly arises from pulse shaping, pulse skipping due to dead time, and voltage drops across switching devices. The second part presents a novel carrier-based Minimum-Loss Discontinuous PWM (MLDPWM) scheme. By analyzing clamping region boundaries, the method applies zero clamping to extend the clamping interval near peak current levels.
