About the high-frequency interferences produced in systems including PWM and AC motors

This work analyses the operation of inverter-fed asynchronous motor drives accompanied by high-frequency interferences caused by parasitic currents of the common and differential modes. These emissions propagated by conduction and radiation may unfavorably affect the operation of nearby telecommunication and signal cables and various low-current devices. The study of these phenomena is based on theoretical considerations and numerical analysis.
