摘　　要：为实现一种结构简单、高效、高频、低电压应力,易于控制的软开关三相逆变器,提出一种新型的三相谐振极型逆变器,它可以实现逆变器的主开关和辅助开关都能实现零电压开关和零电流开关,谐振电路功率小,与传统讨论的辅助谐振极(ARC-PI)逆变器不同,它避免了ARCPI使用的2个大电容,没有中性点电位的变化问题。它的三相谐振电路之间是相互独立的,这就使得逆变器易于应用各种控制策略。选取一相电路,对其工作原理进行了分析,给出了不同工作模式下的等效电路图和最优电路设计。仿真和实验结果都验证了原理的正确性。In order to realize a simple topology, efficient, high frequency, low voltage stress, easy to control soft switching three phase inverter, this paper introduces a novel resonant pole three phase inverter, which realizes ZVS and ZCS of the main switches and auxiliary switches and possesses small power auxiliary circuit and full PWM capa- bility. The circuit avoids the two bulk capacitors in traditional auxiliary resonant commutated pole inverter （ARCPI） and eliminates the center tap potential variation problem of ARCPI. The inverter possesses the advantage of decou- pling the resonance circuit of each phase,and can implement various control schemes easily. The operation principle of one phase circuit is analyzed, and the equivalent circuit and optimum circuit design at different operation modes are given. Simulation and experimental results are provided to verify the theoretical analysis.
