用于直流偏置正弦绕组电流磁阻电机的四桥臂变换器

This paper proposes a novel four-leg converter topology and the corresponding SVPWM strategy for a reluctance machine with DC-biased sinusoidal winding current. Compared with the traditional open-winding inverter topology, the number of the power devices and gate driver required for the four-leg converter topology are reduced by one-third, and the power loss is reduced. With the proposed four-leg ...
