Please provide a clear explanation as to why the Filter section (Flywheel Circuit) of the SMPS is a Passive LC Network as opposed to a Passive RC Network? You will need to research this. Perhaps it has to do with the size of the components, perhaps it has to do with the heat dissipation of the components? Explain how the high speed switching device (MOSFET) has revolutionized the SMPS, making possible the development of high efficiency SMPS and very small designs as compared to conventional Linear Regulators.
