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 ...
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 ...
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 ...
