通过T型电路连接至直流母线电容的中点

'。新型功率变换器不仅可以实现三相四桥臂变换器的所有导通方式，也可以通过控制连接在

和

'中间两个功率开关的导通实现变换器的多电平输出。根据新型功率变换器的运行状态，设计了针对新型功率变换器的分区电流斩波控制和直接瞬时转矩控制方案。在750 W 12/8三相开关磁阻电机上对新型功率变换器进行了实验验证。结果表明，与常规不对称半桥变换器和三相四桥臂变换器相比，稳态下，新型功率变换器结合提出的斩波控制和直接瞬时转矩控制方法具有更好的转矩脉动抑制效果，动态过程的调节时间更短，电机效率更高。

Abstract

To address the inability of the asymmetric half-bridge converter to enable multilevel operation of switched reluctance motors（SRMs）

a T

-type three-phase four-leg converter（TTFC）is proposed.For an n-phase motor

the proposed converter is composed of 2

+4 power switches

with no power diodes required.The proposed converter is developed from a three-phase four-leg converter（TFC）

with the neutral point

of the TFC connected to the midpoint

'of the DClink capacitor through a T-type circuit.All conduction modes of the TFC can be realized by the proposed converter

and multilevel output can also be achieved by controlling the two power switches connected between the converter neutral point

and the DC-link capacitor midpoint

'.Based on the operating states of the proposed converter

regional current chopping control（RCCC）and direct instantaneous torque control（DITC）schemes are designed.Experimental verification is performed on a 750 W

12/8 three-phase SRM.It is shown by the experimental results that

compared with the conventional asymmetric half-bridge converter and three-phase four-leg converter

better torque-ripple suppression under steady-state conditions

a shorter settling time during dynamic operation

and higher motor efficiency are achieved by the proposed converter combined with the RCCC and DITC schemes.
