Reasons for signal interference inverter frequency reduction and electric shock incidents
This article explores how electromagnetic interference affects power electronics systems, how it is caused, and how it can be prevented. . Inverters are circuits used for converting DC input power into AC output power. With high-frequency switching operations, large dv/dt and di/dt are experienced by the power switches, leading to the generation of EMI in inverters. Image used courtesy of Adobe. . Cause: When the inverter power supply phase is lost, the three-phase rectification becomes two-phase rectification. Traditional strategies struggle to achieve decoupling control. However, model predictive control can address coupling issues by adding decoupling terms during mathematical modeling. . During the use of the frequency converter, if it is found that the frequency converter is subject to signal interference, it is necessary to first determine the source of the interference signal, and take appropriate methods to block the signal interference based on the actual situation.
