Eggtronic expands its EcoVoltas AC/DC architecture family with the SmartEgg ZVS PFC and regulator solution for 75 W to 1 kW power applications. Eggtronic has expanded its EcoVoltas family of high-efficiency AC/DC architectures with the new SmartEgg zero voltage switching (ZVS) PFC...

The circuit presented here is a 300W off-line power factor correction (PFC) boost converter providing a nominal regulated output voltage of 375V @ 0.8A of load current. The project accommodates an input voltage range of 85V AC to 265VAC and uses average current mode control at a fixed...

The circuit described here is a simple PFC controller using the UCC28180 chip from Texas instruments. The controller operates under average current mode control at a fixed programmable switching frequency of 116 kHz. Simple external current and voltage loop compensation, along with...
