JEOLLANAM-DO PROVINCE, South Korea, Dec. 18, 2025 /PRNewswire/ -- Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer ...

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 ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...

Inductor-inductor-capacitor (LLC) serial resonant circuits, as shown in Figure 1, can achieve both zero voltage switching on the primary side and zero current switching on the secondary side in order ...
