Principles for reducing disturbances in static converters
EMC in power electronics - Disturbance reduction, simulation

The reduction of disturbances emitted by a static converter is based on three principles:

• reduction at source, which consists in controlling switching gradients, either through the switching mode, assistance circuits or control;

• minimizing parasitic couplings by acting on the converter's physical topology or adding devices to reduce couplings;

• filtering, which remains essential despite consideration of the first two points, can be optimized in terms of volume and efficiency.
