Linear Technology Corporation’s LT3798 is an isolated flyback controller with single stage active power factor correction (PFC). Efficiencies greater than 86% can be achieved with output power levels ...
A new reference design developed by ROHM Semiconductor uses a single microcontroller (MCU) to control both sides of the AC-DC power supply — the power-factor-correction (PFC) AC-DC converter stage and ...
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 ...
