Common-mode noise reduction in DC-DC converters by common-source type active-clamp technique

Several topologies of active-clamped DC-DC power converters have been proposed previously. This paper compares the common-mode-noise properties of the conventional type using a pulse transformer for a gate driver and the common-source type proposed recently. Using a noise measuring system composed o...

Summary:Several topologies of active-clamped DC-DC power converters have been proposed previously. This paper compares the common-mode-noise properties of the conventional type using a pulse transformer for a gate driver and the common-source type proposed recently. Using a noise measuring system composed of LISN (line impedance stabilization network) and EMSCAN (electromagnetic scanning system), it has been clarified that the common-source type has the superiority on noise reduction.
