Abstract

The authors describe a novel conceptual multistage topology of a sinewave-modulated DC-LFAC (DC-low-frequency AC) power conversion conditioning and processing system, which incorporate a phase-shifting PWM (pulsewidth modulation) series-resonant cycloinverter (inverter-coupled cycloconverter cascade circuit) with a high-frequency AC (HFAC) transformer link. Its advanced hardware of system control implementation uses instantaneous sinewave-modulated voltage regulation and compensation strategies, depending upon load disturbance and input DC voltage fluctuation, as well as an instantaneous power regenerating regulation scheme. A newly proposed breadboard using MOS-gate power transistor modules is demonstrated and experimentally tested for high-power-density AC mini-uninterruptible power supply. This series resonant cycloinconverter with HFAC link, which includes the control function of a bidirectional power flow, is evaluated as an AC power supply system for telecommunication and spacestation/aerospace energy situations in the next generation.<>

新型高频交流链路双向正弦波调制串联谐振功率调节系统

作者描述了一种新颖的正弦波调制DC-LFAC (dc -低频交流)功率转换调理和处理系统的多级拓扑概念，该系统包括一个移相PWM(脉宽调制)串联谐振环逆变器(逆变器耦合环变换器级联电路)和一个高频交流(HFAC)变压器链路。其先进的系统控制硬件实现采用瞬时正弦波调制电压调节和补偿策略，根据负载扰动和输入直流电压波动，以及瞬时功率再生调节方案。介绍了一种基于mos栅极功率晶体管模块的新型面包板，并进行了实验测试。该带HFAC链路的串联谐振环变换器具有双向潮流控制功能，被评价为下一代通信和空间站/航空航天能源场合的交流供电系统
