industrial 3.6kw totem pole pfc application evk
various applications are equipped with ac/dc functions, and the totem pole pfc topology is the standard circuit.the tppfcsic-evk-301 implements a single-phase ac/dc conversion stage in totem pole pfc topology. key components are rohm gen.4 sic mosfets (sct4045dr) as the main high-frequency switching elements, as well as the bm61s41 single-channel isolated gate driver ic. in addition, sj mosfets and auxiliary power supply, among other components from rohm, were utilized to create a high-performance ac/dc circuit for single-phase operation.tppfcsic-evk-301 reaches up to 98.5％ efficiency at 230vac.if this totem pole pfc reference design is coupled with a secondary stage of comparable efficiency, it becomes possible to achieve the 80 titanium target efficiency of power supply products. moreover, this contributes to enhancing the annual performance factor (apf) of air conditioners.
this reference design consists of two boards. each is shown below.
