Description
The TP44100SG-TPPFC520-EVB is a highly efficient single phase Totem Pole PFC (TP-PFC) solution, which is built using the advantages of Tagore Technology’s Superior GaN HEMT TP44100SG. The EVBcan operate over the universal input ac voltage range (90 V to 265 V) providing output power up to 520W with efficiency more than 98%. Such high efficiency cannot be achieved using a standard Boost PFC due to high power loss in the Diode Bridge Rectifier (DBR) at its input. The Totem Pole PFC topology replaces the inefficient diodes bridge with semiconductor switches. Tagore Technology’s “Enhancement Mode High Electron Mobility GaN Transistors (E-HEMTs) with ESD protection” parts have very low output charge (Qoss), while the reverse recovery charge (Qrr) is completely absent. These advantages of Tagore Technology’s Superior GaN part TP44100SG are leveraged here to design this TP-PFC solution with low switching loss and enhanced efficiency.
