这篇论文提出了一种基于GaN的3×3矩阵变换器芯片组，采用驱动微波技术，解决了传统AC-AC变换器中双向开关难以单片集成以及隔离栅极驱动问题，实现了高效率、无电容的功率转换。
power and frequency by bidirectional switches has been expected to be an ultimate AC-to-AC converter because it eliminates limited-lifetime capacitors and achieves high efficiency power conversion even without PFC (Power Factor Control) circuits. However, it has not been practically realized due to the following issues resulting from the abundant components it includes. There has been no existing monolithic bidirectional switch that offers a high blocking voltage with current-handling capability and no compact isolated gate driver that provides a gate signal against a positive/negative voltage reference at every moment. Consequently, the matrix converter with discrete components makes the system large and complicated
