Title: Reducing emissions in the buck converter SMPS
Abstract: Switch mode power supply demands are increasing as the electronics industry requires more DC-DC conversion. In the past, linear regulators have been used to regulate power, but as the difference between supply voltages and desired output voltage increases, they become very inefficient. The buck power supply is efficient in converting higher voltages to lower voltages, but unfortunately in the process, both change in current (dI/dt) and change in voltage (dV/dt) are experienced. These changing parameters can cause excessive emissions in the RF spectrum, in conducted and radiated forms. We examine the modes under which these emissions are allowed to propagate, and investigate techniques used to reduce them.
