A new type of DC-DC converter based on Hybrid-switching Method™ and a novel Hybrid Transformer™ enables a high step-down voltage conversion and provides a regulated output voltage of 1V from a 48V ...

High-voltage buck controllers, which offer the beauty of a design without the cost and difficulty of using a transformer, enhance power-conversion efficiency and enable high output voltages.

Several switching-converter topologies exist for power converters that operate from the ac mains and must maintain a power factor of 0.9 or better. One topology is a boost converter with a control ...

I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...
