Device and Method for reduction of Harmonics in Power Converters

摘要

Electronic Device Power Switching stages to reduce the amplitudes of Undesirable Harmonics generated in the device, in particular in the form of HeartbeatThat includes at least one input filter (1), a Switch (2) Periodic Braking Rheostat which comprises at least two Switches (FR1,FR2) and a multilevel inverter (4) comprises at least four switches in series (T1, T2, T3, T4),Wherein the Inverter (4) is connected directly to the periodic Switch (2) providing a connection by its Midpoint (x = X ') comprises a Pulse generator and frequencyRandom variable to control the switches of the periodic Switch (2) only.
