The conventional active neutral-point-clamped (ANPC) inverter inherits excellent high-frequency common mode voltage (CMV) mitigation ability but with a restricted voltage gain. This letter proposes a novel five-level ANPC inverter that is able to accomplish voltage-boosting within a single-stage dc–ac power conversion. A common ground in the proposed topology not only mitigates the high-frequency CMV but also enhances the dc-link voltage utilization. The proposed topology exhibits lower voltage stresses and higher compactness when compared with a conventional two-stage five-level ANPC inverter. The proposed inverter saves three power switches and one capacitor while enhancing the overall efficiency. Simulations and experimental tests have validated the overall operation, efficacy, and practicality of the proposed ANPC inverter.

新型单级五电平共地-升压型有源中性点钳位（5L-CGBT-ANPC）逆变器

常规有源中性点钳位（ANPC）逆变器继承了出色的高频共模电压（CMV）缓解能力，但电压增益受到限制。这封信提出了一种新颖的五级ANPC逆变器，该逆变器能够在单级dc-ac电源转换中完成升压。提出的拓扑结构中的共同点不仅减轻了高频CMV，而且还提高了直流母线电压的利用率。与传统的两级五电平ANPC逆变器相比，所提出的拓扑具有较低的电压应力和较高的紧凑性。拟议的逆变器节省了三个电源开关和一个电容器，同时提高了整体效率。仿真和实验测试已经验证了拟议中的ANPC逆变器的整体操作，功效和实用性。
