The totem-pole PFC is provided, in a high-frequency working area thereof, with at least two current transformer elements or a center-tapped current transformer element. The waveform of current flowing through the totem-pole PFC during positive and negative half cycles of AC power is sensed via the current transformer elements or the center-tapped current transformer element. Thereby, current waveform for the input inductor during positive and negative half cycles may be realized via the obtained current waveform completely, such that the practical problems originating from the conventional necessity for the establishment of bulky Hall device or another current-sensing unit are solved specifically."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Totem-pole power factor correction circuit","description":"A totem-pole power factor correction circuit (totem-pole PFC) is connected behind an input inductor receiving electric power from an alternating current (AC) power source.
