SiC-based diodes and mosfet s switch extremely quickly with low conduction losses. Thus, from the perspective of efficiency, such devices are ideal for a continuous conduction mode (CCM) boost power factor correction (PFC) converter. However, the cir

SiC transistors can switch extremely fast. Often turn-off di/dt is reduced to limit the turn-off over voltages due to the stray inductances in the commutation loops. Thus, the potential low switching losses are not met. One of the benefits of designs

A winding design approach is proposed for the bearingless ac homopolar and consequent pole motors that utilizes the same coils for both suspension force and torque production. This enables a “pure” bearingless motor design, where the same iron an
