Among all power factor correction (PFC) topologies, totem-pole bridgeless PFC provides the best efficiency; therefore, it is widely used in servers and data centers. However, closing the current ...

A proposed new model for current-mode control retains the strengths of existing models such as ease of use and the ability to capture subharmonic oscillations, while improving on weaknesses like dc ...

Two of the top considerations in data center and server power-supply unit (PSU) designs are power density and efficiency. Meeting the strictest efficiency standard—80 Plus Titanium—is now a minimum ...
