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 ...

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 ...

The phrase power factor frequently is used in the electrical and power electronics industry. For example, home, office, and industrial electrical equipment often is fitted with power factor-corrected ...

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 ...

The commercial sector accounts for 35% of the overall demand, driven by the growing need for efficient power management in office buildings, retail centers, and data centers. Eaton Corporation is a ...

Rohm’s new reference design (REF67004) is capable of controlling two commonly used power converter types in consumer and industrial power supply applications by using a single MCU: critical conduction ...

Power electronics is a key enabling technology in essentially all electronic systems and is increasingly important in the grid interface of renewable energy sources and in efficient electrical loads.
