Two-stage matrix converteris a novel matrix converter,which developes from conventional matrix converter.Besides of adopting many ideal characteristics of CMC,TSMC also has many other merits,such as:fewer power switchings,more simplified clamp circuit,simple and reliable inversion,much simple control strategy,etc.

双级矩阵变换器(two-stage matrix converter，简称TSMC)是一种新型矩阵变换器，它继承了传统矩阵变换器(conventional matrix converter，简称CMC)的诸多理想特性，又具有功率开关器件相对较少、箝位电路大大简化、换流简单可靠、控制算法的复杂性降低等优点。

Some circuits use passive snubbers or active clamp techniques. However, these converters become more complicate.

能量缓冲吸收电路或有源钳位电路方案，由于需要增加多个额外辅助元件，增加了变换器的复杂性。

Nowadays the snubbers in IGBT inverters are traditional clamp RCD snubbers yet, which can convert some energy back to power supply so that the dissipation is low.

目前，在实际IGBT逆变桥电路中，缓冲电路大多还是传统的钳位式RCD缓冲电路，这种电路可以把能量部分回馈电源，故损耗相对较小。

Some circuits use resonant, quasi-resonant, and/or multi-resonant techniques. However, voltage or current stresses in these converters are higher and require the devices of higher VA rating. Some circuits use passive snubbers or active clamp techniques. However these converters become more complicate. Phase-shift ZVS technique has been used in bidirectional DC/DC converters since it can realize ZVS for all switches without auxiliary switches.

谐振、准谐振或多谐振技术方案，变换器的电压电流应力较高，变频控制增加了滤波器设计的难度；能量缓冲吸收电路或有源钳位电路方案，由于需要增加多个额外辅助元件，增加了变换器的复杂性；全桥相移技术方案，由于主电路无需增加额外元件，只需利用相移控制，即可实现软开关，因此引起关注。
