The purpose of this study is that we develop a three-phase inverter with very low noise and very low distorted output waveforms. The results obtained are as follows:(1) Two novel-scheme inverter systems. We have developed two novel-scheme inverter system, i.e. a current-source scheme and a voltage-source scheme. Both schemes have high-frequency (HF) resonant inverters and low-frequency (LF) inverters to unfold dc ripple current or voltage. The HF and LF inverters turn-on and -off at zero voltage or current. Then, the both schemes have very low-noise characteristics.(2) A high-frequency link dual-converter type three-phase inverter system with sine wave current outputs. The system has the feature of a high frequency link which provides the reduction of the size and weight of isolation transformers. The system is suitable for power converters of photovoltaic power generation systems.(3)A dual-converter type three-phase inverter system with sine wave voltage outputs. Although the system requires low-frequency output transformers like conventional systems, the system has the feature of easy expansion to more multiplex systems. Then, we can get large capacity power converters which have the feature of very-low noise and excellent output waveform.

这项研究的目的是，我们开发了一个三相逆变器，其噪声非常低，输出波形非常低。所获得的结果如下：（1）两个新型式逆变器系统。我们已经开发了两个新型逆变器系统，即电流源方案和电压源方案。这两种方案均具有高频（HF）谐振逆变器和低频（LF）逆变器以展开直流波纹电流或电压。 HF和LF逆变器以零电压或电流为单位。然后，这两个方案都具有非常低的噪声特征。（2）具有正弦波电流输出的高频链接双连接器型三相逆变器系统。该系统具有高频链路的特征，可减少隔离变压器的大小和重量。该系统适用于光伏发电系统的电源转换器。（3）具有正弦波电压输出的双连接器型三相逆变器系统。尽管系统需要低频输出变压器（例如常规系统），但该系统具有易于扩展到更多多重系统的功能。然后，我们可以获取具有极低噪声和出色输出波形的功能的大容量电源转换器。
