论文摘要
该论文提出了一种直接的建模方法，用于计算基于gan Hemt的三相和三个水平（3L）主动中性点夹紧（ANPC）逆变器的功率损失分布，用于不同的脉冲宽度调制技术。通过从AC负载的工作条件和GAN功率设备的数据开始，可以分析每个PWM切换期间的传导和开关损失。通过基于电路的电源电子模拟工具评估所提出的分析方法的准确性，该工具应用于不同的基于载体的PWM策略。
The paper presents a straightforward modelling approach to compute the power loss distribution in GaN HEMT based three phase and three level (3L) active neutral point clamped (ANPC) inverters, for different pulse width modulated techniques. Conduction and switching losses averaged over each PWM switching period are analytically computed by starting from the operating conditions of the AC load and data of GaN power devices. The accuracy of the proposed analytical approach is evaluated through a circuit based power electronics simulation tool, applied to different carrier-based PWM strategies.
