提出了一种适用于新能源发电和储能应用的选择性双模脉冲调制高效单相正弦波功率变换电路的系统拓扑结构和控制方案。该功率变换系统由分时工作的正弦波绝对调制升压斩波器和分时正弦波部分脉冲调制全桥逆变器组成，第一级功率调节处理级采用旁路二极管，第二级采用分时正弦波部分脉冲调制全桥逆变器。该功率调节器采用无电解电容直流环节的选择性分时双模脉冲模式信号处理控制方案。介绍了分段分时双模部分正弦波调制方案的双功率调理处理级的独特工作原理，并结合设计实例进行了讨论。此外，本文还提出了一种带旁路二极管环路的正弦波跟踪压控软开关脉宽调制升压斩波器，其中包括一个无源辅助边沿谐振缓冲电路。提出了这种新型功率调节器的新概念工作原理和控制实现，并通过实验和仿真结果对其进行了评价
This paper is aimed at presenting a novel system topology and control scheme of a selective dual-mode pulse-modulated high-efficiency single-phase sinewave power-conversion circuit for the new energy generation and storage applications. This power-conversion system is composed of a time-sharing-operated sinewave-absolute-modulation boost chopper with a bypass diode in the first power conditioning and processing stage and time-sharing sinewave partially pulse-modulated full-bridge inverter in the second stage. The proposed power conditioner is operated by a selective time-sharing dual-mode pulse pattern signal processing control scheme without electrolytic capacitor dc link. The unique operating principle of the two-power conditioning and processing stages with sectional time-sharing dual-mode partial sinewave-modulation scheme is described and discussed with a design example. In addition, this paper proposes also a sinewave tracking voltage controlled soft switching pulsewidth-modulation boost chopper with a bypass-diode loop, which includes a passive auxiliary edge-resonant snubber. The new conceptual operating principle and the control implementation of this novel power conditioner are presented and evaluated through experimental and simulation results
