   Considering Mutual Impacts at Differential Mode and Common Mode Motor Filter Design for PWM Inverters
By Dennis KAMPEN, Nejila PARSPOUR, Udo THIEL [View]
[Download]

Abstract: A deeper design approach for three-phase electrical filters to reduce CM and DM emissions is presented. Equations to consider mutual impact of Common Mode (CM) and Differential Mode (DM) filter design are developed. After introducing a typical drive system and todayâ€™s filter design, the new approach is proposed and proven by experimental results.

   Time Domain Simulation Models for Inverter-Cable-Motor System in Electrical Drives
By Calin PURCAREA, Peter MUTSCHLER, Oliver MAGDUN, Alexander ROCKS, Andreas BINDER [View]
[Download]

Abstract: Electromagnetic Interference (EMI) in Adjustable Speed Drives (ASD) with long feeders are of great significance today. Various simulation models have been developed for inverter, cable and motor. Also different simplifications degrees were adopted to ease the simulation burden. In this paper simplified time domain simulation models for inverter, cable and motor are analyzed, implemented and connected together. The inverter point of view is adopted as it represents the source (dV/dt) of voltage overshoot at motor terminals via long cables. Cable and motor models are added to inverter model forming a single simulation system where the HF-phenomena are reflected accurately. Measurements comparisons are presented to prove the reliability of chosen models. Motor terminal design is realized as an application example for proposed models.

   High-Frequency Induction Machine Models for Calculation and Prediction of Common Mode Stator Ground Currents in Electric Drive Systems
By Oliver MAGDUN, Andreas BINDER, Calin PURCAREA, Alexander ROCKS [View]
[Download]

Abstract: For the calculation of the common mode (CM) ground current in voltage source â€“ inverter fed induction machines a simplified (SHF) and a distributed (DHF) high-frequency equivalent circuit are compared. The SHF circuit needs measured parameters of the electric machines, but gives good results in comparison to the measured CM ground current. The DHF circuit predicts the CM currents purely from calculated HF motor parameters in 2D FEM analysis and is more complicated. The CM currents and HF winding impedances of a 7.5 kW and 240 kW motor are presented.
