AC/DC power-factor correction (PFC) rectifiers are hugely benefitting from GaN FETs. They have very simple topologies; The inductor is the only magnetic part and this is usually a constant-frequency ...

A Bridgeless PFC converter based on a novel switching method eliminates full-bridge rectifiers and helps to reduce the size and cost of switching power supplies. Last month, we described a ...

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 ...

To help conserve energy some utility companies and environmental agencies have developed initiatives and incentive programs to make offline ac-dc converters more efficient. To reduce power line ...
