High power density, efficiency, control simplification, and robustness are highly demanded for power factor correction (PFC) converters. This article proposes a totem-pole rectifier based on the ...

When the PF is low and current distortion in power conversion system is severe, heat is generated in the inductor and transformer containing the magnetic material, and large losses in the power ...

The film follows 16-year-old Richard Harris, a Gitskan Indian, as he assists his father, Walter, a master totem pole carver, ...
