“…First, the input DC-link current to the load must be continuous, since any sudden loss of the current results in large dv/dt due to the DC-link inductor. Second, only two switches must conduct at the same time to follow the utilised PWM pattern [5,[29][30][31][32]. The PWM-CSRs are often accomplished within a simple LC low-pass filter [28,31].…”

Fossil fuel prices and air pollution impel many countries to concentrate on renewable energy sources, of which wind energy is considered to be a pillar. Owing to the numerous advantages when compared with its three-phase counterpart, fivephase direct-drive permanent magnet (PM) generators are a key area of focus in power generation with renewable and wind energy systems. The generator output requires a converter, such as an AC-DC rectifier, to match load requirements. The objective of this work is to generate in real time the gating signals of a fully controlled five-phase, line-commutated rectifier, fed from a five-phase PM generator. A mixed-reality environment is used to implement the gating signal generation algorithm for the five-phase rectifier, where the required gating signals are successfully generated, even with some distorted prototype generator voltage waveforms. The performance of the rectifier is investigated practically and validated by using the MATLAB/SIMULINK platform. Moreover, a comparison with a five-phase pulse-width modulated current source rectifier in terms of losses, size, weight, and cost is presented.

“…Having the ability to block voltages in the forward and reverse directions (symmetric blocking) generally limits other performance metrics. However, a symmetric gate-commutated turn-off thyristor (SGCT) has been developed and commercialized for many years [32], [33]. For example, SGCT devices rated for 6.5 kV are incorporated into medium-voltage current source drives by several companies, providing better performance with fewer semiconductor devices (IGBT multilevel inverter design).…”

Axial flux ironless permanent magnetic synchronous motor (AFIPMSM) is a new permanent magnetic motor. It has many advantages, such as little volume, low mass, low lost, high power density, no cogging torque, and the sinusoidal back EMF. It gradually becomes the good choice in drive system. However, because of the coreless structure and the long air gap, the winding inductance is small, which causes the current is not continued with the PWM control based on VSI. On the other hand, the armature reaction is so small that it is difficulties to weakening flux. The motor only be working under the base speed. To solve this problem, a novel speed control strategy to operate a current source inverter (CSI) driven AFIPMSM. And a modified dc-dc converter is used to boost the voltage of DC-link, which can extend the operating ranges of speed. Simulation and experimental results confirm the validity of the proposed control method.
