“…The level and propagation path of the perturbation depend on the dv/dt and circuit properties [3]. The participation of each component and the value of parameters in the EMI propagation change during a typical converter operation [4], [19]. Consequently, the transfer function is variable.…”

“…Numerous publications are dedicated to the control of circulating currents that occur in parallel operated inverters, which, besides the CM (zero‐sequence) component, also contain positive‐ and negative‐sequence components. In this context, Refs present the control of circulating currents in two parallel connected GTO inverters, three‐level neutral‐point clamped inverters, and back‐to‐back connections of the three‐phase PFC rectifier and inverter stages. Subsequent research focused on generalized mathematical modeling and control of circulating currents and the extension of existing models to systems with independent DC links .…”

This paper presents a method to control the ground current in a back‐to‐back connection of three‐phase T‐type rectifier and inverter stages if operated from a three‐phase mains with a grounded neutral point and a star‐connected three‐phase load with grounded star point. The proposed control scheme requires a ground current sensor and a single control loop, achieves a closed‐loop control system bandwidth of 1.7 kHz, and does not interact with the existing input phase current control system that is used to achieve sinusoidal mains currents. According to the presented experimental results, an effective reduction of the rms ground current from more than 200 mA (without controller) to less than 3 mA (with the proposed control scheme) is realized. © 2018 Institute of Electrical Engineers of Japan.

“…V cm noise is a major concern in the applications where high voltages and power levels are required, as they typically give high dV/dt and have high parasitic capacitance. The analysis of the Common Mode (CM) EMI and the possible solutions are very widely treated in the literature and the industrial applications of three phase inverters [3] are the most analyzed; anyway the origin of the problems and the general approaches to noise mitigation are also valid for different applications. It is known that the zero switching states of the inverter control imply larger common mode voltages with respect to that of the non-zero switching states.…”
