比较了交错零电流转换逆变器(IZCTI)和硬开关交错逆变器(IHSI)两种交错电压源型逆变器(VSI)的拓扑结构。在开关轨迹中提出了IZCTI的零电流转变，并与硬开关轨迹进行了比较，以评价开关损耗的降低。然后设计了四脉冲实验来评估零电流转换时的开关损耗，并给出了实验结果。对于IZCTI，提出了一种基于谐振电路的相间电感选择原则。在此基础上，搭建了两种拓扑结构的1kW单相逆变器小型化样机，验证了两种拓扑结构及其技术的有效性。从效率、功率密度和电磁干扰性能等方面对IZCTI和IHSI进行了综合比较。
This paper presents a comparison between two types of interleaved voltage source inverter (VSI) topologies, an Interleaved Zero-Current-Transition Inverter (IZCTI) and an In-terleaved Hard-Switching Inverter (IHSI). Zero current transition in IZCTI is presented in switching trajectory and compared with hard switching trajectory to evaluate the switching loss reduction. Then four pulse test is devised to evaluate the switching loss in zero current transition, and experimental result is shown. As for IZCTI, an inter-phase inductance selection principle is proposed based on resonating circuit. Moreover, a scaled-down version 1 kW single phase inverter prototypes of both topologies are built to demonstrate the validity of topologies and their technique. A comprehensive comparison between IZCTI and IHSI is presented in terms of efficiency, power density and EMI performance.
