本文提出了如何实现三相输入输出的高频交流环节变换器达到95%的高效率。所提出的控制方法是基于无谐振的虚拟变流器系统控制方法。本文提出了两种新颖的方法。首先，提出了降低开关损耗的方法。该方法无需辅助电路即可实现机侧变流器的零电压切换。其次，该实验转换器使用反向阻断 IGBT (RB-IGBT) 代替串联二极管来实现交流开关。通过使用 PSIM 的损耗分析和实验结果提到了 RB-IGBT 的影响。最后通过实验验证了采用RB-IGBT用于AC/AC直接变换器的好处。通过 RB-IGBT 的 1.5 kW 实验系统证实了该方法的有效性。得到了电源线侧电流和发电机侧电压的干净的正弦波形，以及94.7%的最大效率。 RB-IGBT 的效率提高了 1.9 个百分点。对于具有 1 kW 级变压器系统的 AC/AC 转换器，效率约为 95%，非常高。此外，本文还展示了 1.5 kW 感应电机的电机驱动特性
This paper proposes how to realize high efficiency of 95% for the high frequency AC link converter of three-phase input and output. The proposed control method is based on virtual converter system control method without resonant. Two novel approaches are proposed in this paper. First, reducing method of a switching loss is proposed. The proposed method realizes zero voltage switching for generator side converter without auxiliary circuit. Second, this experimental converter uses a reverse blocking IGBT (RB-IGBT) instead of a series connection diode to realize the AC switches. The effects of the RB-IGBT is mentioned by the loss analysis using PSIM and experimental results. At last, the benefit of adopting the RB-IGBT to the AC/AC direct converter is verified through experiments. The efficient of the proposed approach are confirmed through 1.5 kW experimental system with the RB-IGBT. The clean sinusoidal waveforms for power line side current and generator side voltage, and the maximum efficiency of 94.7% are obtained. The RB-IGBT improves the efficiency of 1.9 point. The efficiency of around 95 % is very high in case of AC/AC converter with transformer system at 1 kW class. In addition, the motor drive characteristics with 1.5 kW induction motor are also shown in this paper
