An Experimental EMC Investigation of On-Board Interleaved Buck Converters

On board a satellite, there are different devices that operate from common energy source called power bus. Since many connected to the same bus and they in close vicinity of each other, it is important able function adequately electromagnetic environment satellite without introducing intolerable interference other devices. On-board often require voltage levels function, this produced by switching-mode supplies (SMPS). Their operation guarantees less loss during conversion; however, also emit conducted radiated noises into direction payloads. In case multiple SMPS powered bus, we can interleave their switching periods. Thus, will cancel out on input. study, going demonstrate noise reduction interleaving method with setup consisting two DC-DC converters simulated
