“…Passive [16,17,19,25] and active [21,40] filters at the inverter output or at the motor input have been proposed to mitigate overvoltage at motor terminals. In addition, specific PWM control strategies have been proposed to avoid overvoltage greater than 2 pu [11,20,34].…”

Key points in the development of More Electrical Aircraft (MEA) are currently DC power distribution in higher voltage levels (540 V) and the use of disruptive technology such as Wide BandGap (WBG) semiconductors in power inverters. Using WBG components (SiC and GaN) increases the power converter mass density. However, fast switching of WBG components (tens of kV/µs) induces voltage transient overshoots due to parasitic elements within the inverter. In addition, propagation and reflection phenomena along the harness connected to this inverter, even for small lengths, cause a significant voltage overshoot across the loads. Such overvoltage in Adjustable Speed Drives (ASD: association of inverter, harness and motor) supplied by the new HVDC 540 V aeronautical network could be fatal for the Electrical Insulation System (EIS). This paper proposes a fast and accurate modeling methodology to predict transient overvoltage; it allows us to analyze the impact of SiC inverter technology on overvoltage at motor terminals.

“…Three-phase back-to-back inverters VSD with CM path to ground cancel each other. Such CM-voltage-reducing PWM strategies have been proposed for three-phase matrix converters [7], [8], dual converters for open-end windings motors [9], and single two-level [3] and multilevel inverters [10]- [15], usually with drawbacks regarding the DC bus utilization or output power quality (current ripple, motor overvoltages in long cable applications) [16], [17]. Indeed, CM cancellation is performed by simultaneous switching in opposite direction of two legs, resulting in increased phase-to-phase voltage steps.…”

This paper presents a PWM strategy for the cancellation of common-mode (CM) voltage generated by three-phase back-to-back two-level inverters. This method theoretically provides complete elimination of the CM voltage by synchronizing all the commutations of one converter with commutations of the other one, so that the overall resulting CM voltage does not vary. The degrees of freedom of this strategy are studied and an experimental implementation is carried out on a 15 kW motor drive prototype to validate the method effectiveness. Taking into account dead-time compensation, measurements in time and frequency domains show that the CM voltage is strongly reduced and that more than 15 dB reduction is achieved in a wide frequency range.
