The current study aims at investigating a Single Ended Primary Inductor Converter Power Factor Correction (SEPIC PFC) circuit of low power applications such as the adapters of laptops and mobiles. The SEPIC PFC is designed in CRitical Conduction Mode (CRM) to drive 30W load. A closed loop control circuit is designed to maintain 15V-DC constant output voltage with Constant On Time (COT). The designed circuit is validated by LTSPICE software with a switching frequency up to 260kHz. A Zero Current Switching (ZCS) for the power switch is achieved, thus reducing the switching losses. The design considerations of SEPIC PFC are discussed. The simulation results show that the proposed design has nearly a unity power factor and a satisfying efficiency result over the line voltage range.

Obecne badanie ma na celu zbadanie obwodu korekcji współczynnika mocy konwertera indukcyjnego z pojedynczą koncówką (SEPIC PFC) w zastosowaniach o niskim poborze mocy, takich jak przejsciówki do laptopów i telefonów komórkowych. SEPIC PFC został zaprojektowany w trybie krytycznego przewodzenia (CRM), aby zasilac obciązenie o mocy 30 W. Obwód sterujący z zamkniętą pętlą jest zaprojektowany do utrzymywania stałego napięcia wyjsciowego 15 V DC przy stałym czasie włączenia (COT). Zaprojektowany obwód jest walidowany przez oprogramowanie LTSPICE z częstotliwoscią przełączania do 260kHz. Osiągnięto przełączanie zerowego prądu (ZCS) dla przełącznika zasilania, zmniejszając w ten sposób straty przełączania. Omówiono zagadnienia projektowe SEPIC PFC. Wyniki symulacji pokazują, ze proponowana konstrukcja ma prawie jedność współczynnika mocy i zadowalający wynik wydajnosci w całym zakresie napięcia linii.
