Low-Cost Low-Power Test-Bed for Experimental Investigation of Common-Mode Chokes for High-Power Applications

Simulation Model of Common-Mode Chokes for High-Power Applications

“…The results of the simulations are compared to experimental results that have been presented in a previous publication with a related but different focus [15]. In [15], a series of tests has been reported to show the feasibility of a low-cost method for experimental investigation of such common-mode chokes of inverter-based drive systems of several hundred kW.…”

“…Furthermore, an additional series inductance was included, representing wiring inductance. For the test setup used in the work presented here (Section IV) the value of this inductance had been identified to be 739 nH [15].…”

“…In [15], a series of tests has been reported to show the feasibility of a low-cost method for experimental investigation of such common-mode chokes of inverter-based drive systems of several hundred kW. In this paper, we only review what is relevant for the experimental results we are using for verification of the proposed simulation technique:…”

“…6. Test setup for measurement of common-mode currents with and without common-mode chokes: one motor terminal connected to one inverter leg and additional capacitors with capacitance Ca connected at the motor terminal [15].…”

“…8 and 9 illustrate how the comparatively large value of the choke inductance significantly reduces the ringing of the ground current by approximately one order of magnitude. For further discussion of these results, we refer to [15].…”
