摘要： In a power integrated circuit, a voltage-type single-phase full-bridge conversion circuit is used as a basic unit. The basic unit includes a level-shift-type gate drive circuit. An integrated single-phase multi-level conversion circuit is formed by connecting basic units in series. An integrated three-phase multi-level conversion circuit is formed by connecting three basic units in parallel or by connecting three sets of serially connected basic units in parallel. Since the output multi-level voltage waveform of the integrated single-phase or three-phase multi-level conversion circuit is low in harmonic content, it can constitute a single-phase or three-phase power converter without use of a passive filter.
摘要翻译：在电力集成电路中，使用电压型单相全桥变换电路作为基本单元。基本单元包括电平移位型栅极驱动电路。通过串联连接基本单元形成集成的单相多电平转换电路。通过并联连接三个基本单元或并联连接三组串联的基本单元，形成集成的三相多电平转换电路。由于集成单相或三相多电平转换电路的输出多电平电压波形谐波含量低，所以可以构成单相或三相电力转换器，而不使用无源滤波器。
