Evaluation of DC-link voltage ripple in five-phase PWM voltage source inverters
The Journal of Engineering, 2019 This paper presents the analysis of the DC-link voltage switching ripple in five-phase PWM voltage source inverters with balanced load. The analysis is particularly important for the design and selection of a DC-link capacitor making it possible to meet ...

A rotating arc plasma invertor [PDF]
, 1987 A device is described for the inversion of direct current to alternating current. The main feature is the use of a rotating plasma arc in crossed electric and magnetic fields as a switch. This device may provide an economic alternative to other inversion methods in some circumstances.

Three-level GaN inverter with SiC diodes for a possible three-phase high power solution
The Journal of Engineering, 2019 GaN device is a potential alternative to SiC as a wide band gap device. At present, there are almost no high-voltage GaN devices above 650 V, which makes an inverter design difficult for three-phase input using the standard two-level (2L) inverters ...
