Large flywheel energy storage systems up to megawatt/sub-second range are needed to supply or absorb transient power for pulse loads. Due to its advantages, high power electrically excited synchronous motor is usually preferred in these systems. The Field Oriented Control and Direct Torque Control schemes are two kinds of effective methods used to achieve a stable DC-link voltage. This paper compares...
This paper proposed a novel control scheme for rectifier in 3-level neutral-point-clamped (NPC) converter for propulsion of high speed maglev train. In rectifier, the voltage and current are regulated by closed-loop in d-q reference frame. The fluctuation of neutral-point voltage is analyzed, and a new SVPWM modulation strategy is presented to make the NP voltage balance. The performance of rectifier...
