Design of current sources for load common mode optimization [PDF]
Journal of Electrical Bioimpedance, 2018 Bioimpedance measurement systems often use the Howland current sources to excite the biological material under study. Usually, difference or instrumentation amplifiers are used to measure the resulting voltage drop on this material.

IEEE Open Access Journal of Power and Energy, 2023 Common-mode voltage and current in an electric machine are undesirable. Although the strategic placement of a common-mode inductor and dc input side capacitors may reduce the common-mode current produced by an electric drive system, the effectiveness of ...

Common-Mode Currents and Printed Circuit Boards [PDF]
13th International Zurich Symposium and Technical Exhibition on Electromagnetic Compatibility, 1999 Common-mode (CM) currents through cables attached to printed circuit boards (PCB's) are often the main cause of interference and may even dominate the direct radiation of the board. In this paper, the authors predict the coupling between the differential-mode (DM) circuit on the board and the CM circuit in a Bersier setup, by means of a rapid ...

Analytic Radiation Models of a Microstrip Line on a Slotted Ground Plane [PDF]
Journal of Electromagnetic Engineering and Science, 2022 In this Letter, analytic models for EM radiation analysis of a microstrip line (trace) on a slotted ground plane are proposed. The EM radiation is separated by the effects of trace and slot, and analytic radiation models for each effect are presented ...

A New High Gain AC-Decoupled Transformerless Inverter for Photovoltaic Applications
Journal of Applied Science and Engineering, 2022 Transformerless inverters are prominently used in the single-phase grid-connected system due to their reduced size, weight, and high efficiency. Common-mode leakage current is the main issue of transformerless inverters, which has to be mitigated.
