AI Customer ServiceInverters using soft-switching are called resonant inverters. Inverters are circuits used for converting DC input power into AC output power. Inverters find application in battery-powered systems, renewable energy systems, uninterruptible power supplies, motor drives, etc.
Figuring out how to reduce electromagnetic interference in inverters is something that designers must devote considerable attention to. There are various techniques to choose from; EMI filters are one such method, generally used in the input side as well as the output side of inverters to reduce EMI.
Therefore to avoid resonance being excited we must change either k or m or both. In general, the fundamental consideration for an example SDOF system is to make the system as stiff as possible, increase k, but keeping the mass as low as possible, decrease m.
Proper grounding: Ensure that the inverter is properly grounded to minimize the risk of EMI. Quality components: Use high-quality components in the inverter circuit to reduce EMI. Shielding: Shield the inverter and cables with metal casing or braided shielding to reduce the emission of EMI.
Basically put, how do we avoid resonance This is simple in theory, but not always so simple in practice. If the natural frequency is Then, And where the undamped natural frequency is , Where k is stiffness and m is mass. Therefore to avoid resonance being excited we must change either k or m or both.
The guidelines guarantee that: The inverters do not generate excessive noise and harmonics, which can contaminate the AC grid voltage. The inverters are immune to electrical and magnetic noise from other sources and provide reliable operation in an environment of high electromagnetic noise.
